I think a reasonable quorum already said this, but NFS is still good. My only complaint is it isn’t quite as user-mountable as some other systems.

So…I know you said no SAMBA, but SAMBA 4 really isn’t bad any more. At least, not nearly as shit as it was.

If you want a easily mountable filesystem for users (e.g. network discovery/etc.) it’s pretty tolerable.
