> Bluetooth may work or not work
In my 4yrs+ of using Linux, this has never been a problem for me.
> Apps may be compatible or not with Wayland
App developer's fault. Besides xwayland bridges that gap.
> Power consumption may not be efficient
Use Wayland for GUI apps. Use more cli applications.
> Computer may not resume from sleep
This one I have to concede. It's been wonky but for me now seems reliably stable with my setup.
> The browser may burn CPU when playing videos
This one has been fixed recently. Chromium and Firefox already support hw video decode with Firefox set to make it the default configuration in FF 103.
> clipboard not being always shared
I don't know what your setup is but gnome's gpaste clipboard experience is 100x better than any OS I've used before.
> file managers not sharing bookmarks data across them
Have never come across this use case. Why would you expect this to be a feature? Even Windows doesn't support this feature when you swap file managers.
