Keep running Ubuntu for servers, even consider using Pro if pricing is suitable for your use case. 10 years of support is pretty good these days. As for desktop: Arch Linux if you like tinkering and need "bleeding edge" software; use Fedora Linux, if you want to be on "leading edge", and want system that you install and it just works; Debian for something more stable. Linux Mint is decent too, but their plan for Wayland is not known yet, if that's something that important for you.
