A lot of people like having a NAS VM like OpenMediaVault or TrueNAS that handles their drives via passthrough.
It sounds like you would prefer a lighter weight option—the way my storage is set up is ZFS pools handled by Proxmox itself, then bind mounted from the host into containers that handle the actual file sharing portion. I have separate, self-configured containers for Samba and NFS, but there are turnkey options in the proxmox template menu if you’d prefer.
