I’d also suggest Arch assuming one has patience for some tinkering. Getting familiar with the Arch Wiki and the other resources that exist is quite useful even with other distros! Not to mention the better understanding of the system gained simply by following the installation guide.

Even if one doesn’t stick with the distro, the things learned setting it up will be useful down the line as well. The experience would also be very different from Debian based things, so it could be fun for a distro hop!
