There’s also the Wayblue family of Wayland distros, based on Ublue.
It’s hard to say for certain whether a distro will work for your hardware, even the Nvidia-specific images can have bugs related to the Nvidia drivers or their interaction with compositors.
I’ve used NixOS for a year.
I also tried Fedora Sway Atomic for a week or so. It mostly worked well, but I eventually found that it’s really hard to use Nix for development on a graphics application, because linking with the system Vulkan drivers is near impossible. The loader used by Nix’s glibc will ignore FHS locations. That seems to rule out a lot of the benefits of using Nix.
So I gave up on using Nix + Fedora as a failed experiment and went back to NixOS.
My wish list for Nix, Wayland, and Sway is pretty long. I kinda wish I had the time to make a new distro.
