Oh wow. That's wide open then, just about any of them. I run Mint on older mac hardware (happily cruising along on an 11" MacBook Air), I'm a sucker for Ubuntu's default look and feel a lot of the time - and they have a pretty large user community (as do all the major distros), and love Fedora too.
One note - a lot of the distros are Debian based (Mint/Ubuntu/etc.) vs. Red Hat (Fedora, Asahi - M1/2 Apple hardware Fedora, etc.) vs. Arch Linux.
If you're just getting started it's probably easier to get into the Debian world, but I'd advise you to dip your toes in other distros too unless you just deeply fall in love with your first pick.
(I have my 80 year old neighbor happily running Mint on their old computer to save them from having to buy a new Windows machine.)
I'll add that Libre Office can be great but if you already have an ecosystem you like, most of those have online editors too which can handle most of the average user needs.
