Just to throw another option in: Lxc are containers too. And they are the other major option proxmox comes with.

It feels more like bare metal installations, but are more lightweight and share there ressources they do not use.

I never got why having Proxmox and one VM with several docker containers except I absolutly don’t want to deal with installations at all.

On the other hands I wanted to learn about linux and the basics of handling proxmox.
