Debian Stable or Testing. Runs on anything, and Stable - especially - will not let you down. Ubintu, Elementary and dozens of others are downstream of Debian. Bookworm is a great experience, so why not go to the source?

“Testing” is described as containing packages that are still in the queue to be accepted into Stable.

“Unstable” branch is all the newest stuff, whether it works or not.

If you’re in school for anything computer-related, once you’ve settled on a distro, you could also start playing with Gentoo.
