fire7side I wont reccomend debian for the reason that its not usable in modern day.. its for grandmas who are slow with current world technologies
If you have multiple monitors with high refresh rates and different resolutions, and different refresh rates, then you want wayland, not x11 or xorg
If you want to scale your 100incher 4k display so that you can sit back in couch and read the text (150% scale or something) you want wayland
If you have a laptop with one screen then you can go x11/xorg
Now these are not distros its a display server or something
Each distro has many flavors of desktop environments - gnome, kde plasma, cinnamon, xfce, etc etc..
Each one of them has or has not the wayland support.. many are wayland only, many are x11 only.. sure you can go and try to cobble up them to work with anything but thats up to you..
I use KDE - wayland on archlinux.
Arch has up to date packages, latests and greatest, but they are often buggy.. for instance, past 3weeks they broke my mpv media player and now i cant watch in fullscreen because i get flashing white lines on screen..
But, switching up to other linux kernels fixes this bug... so you see, there is always things you will learn when using arch.
I suggest you make a list of applications you need, you want, filetypes you use and see if the distro you choose can satisfy your needs.
Start with virtual machine, install many distros to see if you can use the things you want to use..
Thanks to steam youll be able to game on practically any distro, so dont worry about that.
