What are some security tips for your new VPS/idlers/chickens?

in General
I usually do ufw (close all ports except the ones I need to be public facing), fail2ban, restrict login to ssh only, os updates, restrict login to specific IPs only. I also disable ICMP broadcast echo replies.
I'm starting to think for proxmox VPSs I should probably run headscale or tailscale and only ever have the admin interface on a private network right? Though I have it locked to only accessible by specific IPs currently, but maybe that's not enough.
Seems like with the rise of automated exploit scanners, the safest route is probably just keeping everything behind headscale/tailscale unless it needs to serve public web traffic?
I mostly run Ubuntu/Debian/Proxmox.
Anything else you guys recommend?
