Install Proxmox on bare metal, like you said.
Then use a debian container (CT) for docker, not a VM. Me? I'd use Fedora for podman, but you could use any base Linux container. No need for the additional overhead of a full VM. This is what I do.
A place to discuss everything related to Container platforms and runtimes. Docker, LXC, Podman, OpenShift, OCI, and more.

Oh, wow! I didn't even realize you could do that (install a container engine in a container). I will have to check that out. Thanks for the tip!
It depends a bit on the filesystem that you are choosing for proxmox however. Afaik there are still problems with zfs as the host filesystem and docker in an lxc. the general recommendation is to use an extra virtual disk that is ext4 formatted for /var/lib/docker
.
Have you had a chance to try this out yet? If so, please add another post with your experience.
