+1 synology has been a surprisingly competent docker home server. I decided I wasn't interested in any of the services that require an account with them and was pleasantly surprised everything works fine without signing into any synology services. I thought about building something but I wasn't confident in any of the free NAS OS's on offer. Synology has a nice interface for managing users, containers, and sends me drive health reports on its own email address via SMTP. Low drama environment.
I love Immich [0] for photos, Jellyfin [1] works great for music and movies, just spun up a memos container for notes. For documents and stuff I would use dropbox for I just FTP into with Cyberduck or Filezilla.
