Nvidia or not, stick with X11 until you have a reason to use Wayland.
I need Wayland for my packaging work, and one of my devices requires Wayland so I use it for that and it’s a decent experience, but Wayland still has drawbacks (weaker automation API, some programs still don’t work) so I wouldn’t recommend switching off X11 unless you have a reason.

The only reason I have is the weak security model of X, and maybe early-adopters syndrome
