Been using Nvidia+Wayland for years now, even on an optimus laptop.
I'm convinced that many these people saying Nvidia has serious issues on Linux must be (by no fault of their own) going by habit and downloading the driver installer .bin from the Nvidia website and trying to install drivers that way. So yes, if you do that you're going to have issues.
Learn to do things the way your distro does them (use a package manager) and most problems go away.
I feel I'm in the same boat. For several months I've been thinking my GPU was on its way out (it's a pretty old 2080 now). My desktop freezes randomly. I can log into it remotely but all the usb devices stop working and the screen goes blank. l took a good look at the logs and noticed a bunch of pageflip timeouts followed by usb disconnections. I later discovered the Nvidia forums seem to have many recent complaints (with similar logs) especially around their latest drivers and Plasma + Wayland compatibility.
