LXC via Proxmox is great for stateful deployments on baremetal servers. It's very easy to backup entire containers with the state (SQLite, Postgres dir) to e.g. NAS (and with TrueNAS then to S3/B2). Best used with ZFS raid, with quotas and lazy space allocation backups are small or capped.
Nothing stops one from running Docker inside LXC. For development I usually just make a dedicated priviledged LXC container with nesting enabled to avoid some known issues and painful config. LXC containers could be on a private network and a reverse proxy on the host could map to the only required ports, without thinking what ports Docker or oneself could have accidentally made public.
