Inspired by this comment to try to learn what I'm missing.

Cloudflare proxy
Reverse Proxy
Fail2ban
Docker containers on their own networks

Another concern I have is does it need to be on a separate machine on a vlan from the rest of the network or is that too much?

Disable password authentication on SSH

Enable firewall and block all ports you're not using(most firewalls do this by default)

Switch to a LTS kernel(not security related, but it keeps things going smooth... Technically it is safer since it gets updated less often so it is a bit more battle tested? Never investigated whenever a LTS kernel is safer than a standard one)

Use Caddy to proxy to services instead of directly exposing them out

HTTPS for web stuff(Caddy does it automatically)

Caddy or any other (reputable) reverse proxy. I think Nginx Proxy Manager would be best for beginner thanks to GUI.
