I use zfs with Proxmox. I have it as a bind mount to Turnkey Fileserver (a default lxc template).
I access everything through NFS (via turnkey Fileserver). Even other VMs just get the NFS added to the fstab file. File transfers happen extremely fast VM to VM, even though it's "network" storage.
This gives me the benefits of zfs, and NFS handles the "what if's", like what if two VMs access the same file at the same time. I don't know exactly what NFS does in that case, but I haven't run into any problems in the past 5+ years.
Another thing that comes to mind is you should make turnkey Fileserver a privileged container, so that file ownership is done through the default user (1000 if I remember correctly). Unprivileged uses wonky UIDs which requires some magic config which you can find in the docs. It works either way, but I chose the privileged route. Others will have different opinions.
