I'm using Nvidia on Wayland Gnome right now and the experience has been pretty stable. I didn't come across any bugs but my main issue is that Wayland makes screensharing way too difficult and hotkeys for background apps not work. Discord straight up doesn't support screensharing on the official app with Wayland.
Screensharing has improved a lot over the last couple of years. Pipewire and XDG Desktop Portal are the tools you want to look into. You can run an in-browser test of screen sharing at https://mozilla.github.io/webrtc-landing/gum_test.html
