    Why would you leave PermitRootLogin to yes? Doesn’t really matter, if root ca nit login anyways?!

    Just like you don’t really need UFW, not really harmful and for piece of mind :)

    But to be honest, I am no expert either. I look at your config and think, just leave everything at default besides these twos:

    PubkeyAuthentication yes PasswordAuthentication no

    Things like

    MaxAuthTries 3

    don’t matter for public key auth.
