Just wait. There are VERY few devices right now that can even realistically use WIFI6 and generally it is only useful to large environments. If you had some reason like remote VR to use it then it would be different. But really you are not likely at all to even be able to use it.
If you were upgrading your hardware because it was dated and it didn't work as well or you had a need it would be different. No reason to spend the money now when it really doesn't benefit you.
