i switched my desktop to wayland a few months ago due to weird performance issues in some 3D applications
it went mostly flawlessly, i haven't had much if any issues in terms of app support, as long as your wayland compositor supports xwayland, everything should work pretty great!
the application ecosystem isn't as widely developped though, so you may run into issues if you try to use standalone window managers/compositors like sway, hyperland, etc… but besides that, everything's been great for me!
