Ubuntu and Debian should be good, I’m not very aware on truenas to give an opinion.

I personally use Fedora, and it’s been a solid experience too, with the only gripe bring SELinux. I required a fix for SELinux, but it has worked flawlessly since.

However SELinux might make it annoying to work with containers, so you could consider either switching it off, using another distro or using appropriate configurations to work with it correctly.
