Choosing an hypervisor

Hello everyone! During one of those illuminated evenings, I got the idea to move my small server in Scaleway to some more powerful server in Hetzner. If I will make the move, I am thinking of splitting the server in various VMs, to host different services that belongs to different trust boundaries, for example:

• A Lemmy/writefreely instance
• Vaultwarden/Gitea
• Wireguard tunnel to my home infrastructure
• Blogs, and other convenience services

In order to achieve the best level of separation, I was thinking of using VMs. My default choice would be Proxmox, because I used it in the past, and because I generally trust it, however I am trying to evaluate multiple options, and maybe someone has good or better experiences to share.

Other options I thought about are:

• Run everything in Docker. I am going to do this nevertheless, but Docker escapes are always possible, especially with public facing images that I did not write myself and/or that require a host volume.
• KVM directly? I am OK even without a GUI to be honest. I am not aware if there is some ansible module or even better Terraform provider for this, it would be great. (EDIT: I found https://registry.terraform.io/providers/dmacvicar/libvirt/0.7.1 which seems awesome!)
• ESxi? I have no experience with this solution.

Any idea or recommendation?
