Garuda is more user friendly than most arch distros, but you really might want to consider something like bazzite. You can always change the desktop environment and theme as much as you want regardless of distro, although if you’re looking for a Windows -like experience I recommend KDE with it’s default settings.

Debian ships with older but stable packages. It won’t provide you the latest version of your Nvidia drivers, you’d probably have to get them from Nvidias website yourself.
