I’d say 90% of usage can be done without the terminal especially if you just use Linux to browse the web or check email or other things that are mundane.

Anything past that, there is a good chance you’ll have to use the terminal. That said, I think its easier than ever with lots of people making the switch and asking questions on Lemmy or other forums.

I use cloudflare for both my domains. $17 or so each.

Honestly you can spend as little as a couple bucks if you dont care about a name. I like cloudflare but almost any registrar is fine as long as you pay for the domain.
