Personally when I stopped using Ubuntu (this was years ago), I hopped around different Ubuntu distros for a long time. Probably a good place to start, especially since Mint is based on Ubuntu.
After that I used Garuda (fairly user friendly, does require some terminal usage), then Arch, then NixOS, back to Arch, and now I’m pretty happy with Gentoo.
My main piece of advice when doing this: Set up the install to use a separate /home partition. It makes things way easier. You keep all of your configurations and such, just have a different OS under the hood.
