Linux has lots of flavors; and just like ice cream, you can have a scoop, see if you like it, and try another one later.
I’ve been through so many Linux and Unix flavors over the years, it’s borderline absurd. But what was great is that I found a flavor just right for me and my needs, like finding your ideal car. Don’t worry about making the right decision on a flavor at the start, just dive in.
Ubuntu, Fedora, Mint, Pop! OS, Manjaro, elementary OS, Zorin etc are great starting points. You’ll hear people bigging up Arch, Nix, Gentoo, Slackware, Void, etc. There’s are all great in their own way and very well might be the right thing for you but don’t feel pressured to jump in the deep end (unless you love that thing, then be my guest - Arch was a lot of fun getting it up and running for the first time).
The best decision I can suggest is learning about mount points and having a drive dedicated to your files and simply mounting that drive inside your home directory. It means you can wipe and try another distro wherever you like without having to copy your files off and on over and over again.
