If you're seeking something simple to use where you may never need to open the terminal, I'd say ZorinOS(Lite).
You can also test out Debian if you don't mind a bit of tinkering on the terminal. You'll have to add yourself as a user to the sudoers list first thing but there are plenty of 2-second video tutorials on how.
For both distros, if you are searching for support, you'd search "on Ubuntu" and basically the same would apply.
Thanks, I think psst will be it
