Started off by

Enabling unattended updates
Enable only ssh login with key
Create user with sudo privileges
Disable root login
Enable ufw with necessary ports
Disable ping
Change ssh default port 21 to something else.

Got the ideas from networkchuck

Did this on the proxmox host as well as all VMs.

Any suggestions?

You have a good list to start with. Consider adding sshguard or fail2ban in the short term and crowdsec in the long term. Also use lynis on Unix systems and PingCastle on AD systems and see what suggestions those make. Just a few suggestions off the top of my head.
