I'm trying to use the GoPro Hero 7 Black for real estate video (I know this is not really what it is meant for) and it looks very good for the most part. The only thing that is holding it back is the stabilization seems to get confused on slower turns and becomes jerky. On faster turns the stabilization works great and the stabilization is great on all other axes. Here is a link to a video of what I am talking about:
Would it be possible to address this in any way in a future firmware update?

Good suggestion from Fishy, but I'm guessing that in use it might be hard to judge the speed at which it stutters and the speed when it doesn't. The other work around is to turn off stabilisation on shots you are going to be pannning - but this then negates the reason for buying a camera with hypersmooth EIS.
Gopro need to add user selected stabilisation modes - full stabilisation (as it is now) and vertically only (doesn't stabilist horizontal movement but does stabilise vertical movement). The Stabilisation vs panning is an old problem on a number of camera makes with stabilisation (including OIS and IBIS) and often the solution has been these two modes.
Of course the switch would need to be at the top level - you don't want to be burrowing down menus to get to it. Ideally it should be possible to switch whilst recording including from the app so you can get to best of both worlds.
Unfortunately, however, at the moment no fix has been implemented and users will be left with figuring out workarounds until it is fixed. My oersonal workaround was not to get the 7 but that doesn't work for everyone :)

Rumors currently are that the HERO7 cameras will be getting an update in early December. Hopefully we will see more stabilization options brought to the HERO7 Black when the next firmware is released. Until then, we can only try to find "best" work arounds.
So far in my test, I've found that one of the following provide better results when slow panning:
- Turn Stabilization off - obviously this removes the EIS "jump" but requires an extra step and also negates verticle stabilization
- Use 1080p/120fps (16:9) - works well but requires good lighting. Standard Stabilization used by the camera
- Use 4K (4:3)/24fps - works well in lower light but can induce more motion blur. Standard Stabilization used by the camera
- Shutter speed 1/3x the fps - Mixed results but seems to be the "sweet spot" for the best hypersmooth stabilization. Can require finding and setting the appropriate ISO and/or using ND filters. Reduces the camera's ability to adjust to changing light.
I primarily use 2.7K/60fps and have found that setting the shutter to 1/3x the fps (1/240) has many benefits with Hypersmooth Stabilization on the HERO7 Black. Not only does it seem to reduce the frequency of "jumps" when performing slow turns or pans (not completely, but tends to be much better than auto), it also nearly eliminates the blur that can happen in low/mixed lighting.

Of course there's one work around that will really get some peoples hackles upjust suggesting it.
Use a gimbal. Yes I know that this totally goes against the reasons for buying a camera with "gimbal like" stabilisation and adds extra expence but theres places where gimbal like stabilisation doesn't actually work like a gimbal.
- Slow panning - your very problem shows that camera stabilisation cant do what a gimbal can in giving smooth pans.
- Lower Shutter Speed motion blur- if you've used EIS with 24fps while walking around town you've probably noticed all the electric spaghetti you get from the lights and how everything looks a bit blurry. This is the motion blur caused by the slower shutter moving and the EIS being applied after the image is taken. Where the motion blur stopps in one frame is no longer where movement starts in the next so it is a complete jumble of squiggly lines
The gimbal can help reduce all the little hand jitters and keep the camera steadier when the shutter is open . As the image isn't them moved around the motion blur that is in each frame matches seemlessly into the next frame so the electric spaghetti effect gets negated.
- Dips and waves - if you're hand holding the camera then any changes in the orientation of your hand can cause the camera to tilt up or down, pan left or right or accidentally create a Dutch Tilt when that isn't the intention. A gimbal can be set up to either smoothly follow the pans but keep the camera on the same horizontal orientation (i.e. keep looking ahead not to the ground but still turn when you do), smooth out the pans and the tilts (so you can tilt it down to the ground when you want but it's slower and smoother than an accidental jerk) or ignore all pans and tilts and just keep the camera looking in the same direction all the time.

Gimbals are perfect panners??!! NO.
Sure the result is a smooth pan...but it might not be at the rate you wanted or the exact composition at the moment you wanted it. Your vision can be lost and they can be tiring to handle and manage.
The Hero 7 Black is an Action Camera. Used during Action Moving Forward, Hypersmooth truly is gimbal-like.
Low light cinematic dramas and landscapes can be done with a GoPro.
But personally I'd use other devices for that.

However, as the OP already has the HERO7 Black and clearly is looking for best settings/suggestions for using this particular camera in this situation, it's probably best if we address this first.
If purchasing additional equipment is an option, I think @jay-ell has the best overall solution. I've done some real estate property filming using my GoPro Karma and being able to transition from the Karma drone for exterior and then to the Karma Grip for exterior/interior shots was really handy. Not only that, the Karma Grip shots turned out really nice.
The thing about using a Gimbal is they are NOT fool proof. You have to practice with them and learn the behavior or the Gimbal and also how to handle them correctly. If you just throw your camera on the stabilizer and go walking around you are going to be very disappointed in the results. I'm actually becoming much more happy with the HERO7 Black Hypersmooth stabilization than from what I get out of my Karma Grip or FeiyuTech G5 (I actually gave my FeiyuTech away because I have no need for it).
Another option that I didn't mention is getting a long periscoping selfie stick. When you need to do sweeping/panning shots, turn stabilization off and extend the stick and place it on the ground. Many of these sticks have a rubber round nub that you can put on them, which will allow you to slowly spin the camera while keeping the vertical/horizontal plane level.
Hohem makes a pretty cheap stabilizer if you want to try that route and periscoping selfie sticks are pretty easy to find for cheap.
I suggest starting with the simplest and cheapest suggestions and working your way through them until you find the best solution for you. Hopefully you will find a setting or option that is both cheap and effective for getting what you want.
Best of luck!

Of course gimbals aren't perfect. I don't think that there will ever be a sure fire one size fits all solution that covers every possible scenario but it's worth trying to think what the possible solutions are available for each situation.
I also don't think there's ever going to be an instant fix. EIS/OIS/IBIS/Gimbals/Steadicams/Glidecams/Drones all need practice and evolution of techniques to get the best result. None of them are perfect for every scenario - some are more suited for certain usage but not for others.
