I would recommend Linux Mint personally. And there are various reasons why:
Whether you use the tuning m Ubuntu base or Debian base, getting hold of software will be much easier because if something is not in the repo chances are there is a deb for it.
For example I use Vivaldi browser, 1Password and OnlyOffice. Neither is which are in the repos. But they all offer a deb installer on their website. Same goes for TeamViewer and many other non FOSS apps.
Who wants to waste time on arch or wherever trying to figure out how to get his of binarys?
Mint is free of snaps so you don’t have that headache, and can run Fkatpak.
Mint has sane defaults and doesn’t include unnecessary apps. I think I only removed 3 apps to replace with the apps of my choice. The rest of the selection is perfect.
The Cinnamon desktop looks good, is very fast, works intuitively and gets out of your way. Since The Mint Team make Cinnamon you’ve always got the latest and greatest.
Plenty support. Because Mint is based on Ubuntu and Debian there is TONS of information online to help you solve any issue. Plus Mint have a forum.
Reliability and low system requirements. Unlike Gnome desktop, Cinnamon uses less RAM so right off the bat you win back RAM on your system. It’s very fast, light yet good looking and functional. Plus Mint is generally very reliable because the team focus on that.
They will take their time to carefully test and consider something and it’s impact on users before releasing it. For example Wayland. They still use X11 because they are assessing Wayland and switching to Wayland only would break some users systems.
It literally has everything you want in a distro. Where new user or Linux Pro, Mint will suit both and everything in-between
