Go ahead with mint. It's the only distro I know with a fully featured setup wizard that holds your hand through the entire process. I am confident anyone who has used computers can use it.
But honestly, most modern distros are about as difficult as picking up an iOS/android phone for the first time. There are different ways of doing things, but they're still phones and can't be too different anyway. Same with mint, it's just a computer, it isn't all that different.
No it can't be. I'm using fedora right now and it drops me into the GNOME desktop with nothing. The GNOME tours barely count, they just tell you to login to your dropbox or smth.
Have you seen the mint one? It's actually dummies proof. Full "It's my first day on linux" step-by-step guide. Everything from updating, setting themes, backups, installing nvidia drivers is in there. All relevant choices are meticulously explained.
I'm so certain of its coverage, I recommend mint to internet strangers because I genuinely believe it's sufficient even for the lowest common denominator. I can drop mint on any rando and fully trust that the Mint setup wizard will hold their hands through their first day on Linux.
I last switched distros 3 years ago, and the wizard definitely wasn't on popOS or Ubuntu either.
