I'll give a +1 for Mint and Pop_OS!, especially Mint (Cinnamon edition) for people who don't want to learn a new layout either.

Linux mint I guess. As from my experience, it have almost everything needed by a regular user:

• Great application center with flatpak and Flathub enabled out of the box, which already covers almost every application needed by a regular user
• Graphical driver installer
• Ability to install apt packages without terminal
• Good pack of preinstalled applications - it's already possible to do almost everything regular user needs, like browsing the web, working with office documents, reading PDF files and so on
• Driverless printer support out of the box

Also it looks awesome out of the box (especially after recent redesign), and works fine even on not so capable hardware

The only thing I don't really like about it is it being based on LTS release of ubuntu, which may lead to some problems on newer hardware. Still can be fixed by installing mainline kernel and adding ppa repositories, but it's not really easy to do without using terminal

Probably POP_OS to my understanding, I haven't used it much myself but I hear good things in terms of a "Just works" distro.
