My favorite go-to for new users is Fedora. It's a community version of red hat Linux and i have to say the installer and built-in software should get you most the way through out the box.
My next recommendation is Vanilla Debian V12 Bookworm. I like Debian because it's a rock solid distro that's hard to mess up.
Besides the base OS, consider using either a KDE or Gnome desktop. Either should deliver a solid new user friendly UI.
