If you don’t have any experience, then probably FreeBSD imho; Follows unix philosophy, stable, built-in support for ZFS, dns caching, NFSv3 & NFSv4, used as the base system for stuff like OPNsense, freenas and a bunch of other stuff at one point in time or another.
And it’s really well documented.
If you already have a set of linux utilities or a certain distro you really like then go for that. But it’s almost always going to mix-up user and system installations along with needing to learn new stuff for every distro and hoping it’s stable with all the different package managers you will need.
