I run everything on a lean Ubuntu server install. My Ansible playbooks then take over and set up ZFS and docker. All of my hosted services are in docker, and their data and configs are contained, regularly snapshotted, and backed up in ZFS.
I run basically all of the Arr stack, Plex (more friendly to my less tech savvy family then my preferred solution Jellyfin), HAss, Frigate NVR, Obsidian LiveSync, a few Minecraft worlds, Docspell, Tandoor recipes, gitea, Nextcloud, FoundryVTT, an internet radio station, syncthing, Wireguard, ntfy, calibre, Wallabag, Navidrome, and a few pet projects.
I also store or backup all of the important family documents and photos, though I haven't implemented Immich just yet, waiting for a few features and a little more development maturity.
About 30TB usable right now.
