The closest thing to Ubuntu is Debian. But I'd like to throw in a recommendation for Fedora. It includes Flatpak by default (which to me as always been the least objectionable sandboxing system) but nothing comes as a flatpak by default. You have to explicitly choose to use it. Fedora's hardware support is second to none, and even supports in-OS BIOS updates. I highly recommend it.
