I personally just use tldr to figure out how it's done.
It depends on what you install. You can do an arch install without Wayland. I'm currently running x11 on Arch with Wayland also installed so I can switch back and forth at any time.
However, unless you like to spend time learning how Linux works, I'd just go with another distro like Nobara. It will have everything you want pre configured.
The program responsible for logging in and starting your window manager is called the display manager. Sddm is the default for KDE and GDM is the default for Gnome.
Technically, you don't even need a display manager as you could login and start the window manager manually directly from the TTY. That's just mainly useful for when you break something in your display manager config though.
Google constantly does this. Never makes any sense.
