Security operates in layers and ufw is a pretty simple layer to setup. Especially if you only have like one or two services you need exposed on a given system.

Yes every host should only be exposing what it needs to be exposing. UFW is dirt simple too. The amount of protection you gain for the effort is huge
If you don't know, you don't need!
Ufw is really simple, you should.
No take the time to actually learn iptables and then learn how to properly integrate fail2ban with iptables.

So ugh, I run Unraid and port forward plex and a valheim server.
Should I figure this out too?
Without going on a rant. UnRAID doesn't really have a firewall, so you end up deping on a latlyer 2 firewall. And depending on your router, you may be SOL. When you port forward, you basically open the route on fron your router's firewall. At that point, you depend on if the application is secure now the attack vector is as wide as the intention of the attacker. Unraid is a pain when it's down to security anyways.
