If you wanted, and your drives are mounted to the Proxmox host (and not to a VM), try an LXC for the services you are running, if you require a VM then the above workaround would be recommended after backing up your data.
Basicboi config, but it's quick and gets the job done.
I'd originally gone down the same route as you had with VMs and shares, but it's was all too much after a while.
I'm almost rid of all my VMs, home assistant is currently the last package I've yet to migrate. Migrated my frigate to a docker container under nixos, tailscale exit node under nixos too while the vast majority of other packages are already in LXC.
