You are doing more than I am (e.g. synchronized file storage, books, music), but I have radarr, sonarr, overseerr, plex, and supporting apps for movies and tv shows. Plex is available externally through its remote access feature. For the actual request system, I run OpenClaw with an Overseerr extension. This allows me to manage titles remotely via Telegram without any kind of tunnel or SSO. Simple and gets the job done for the solo-user scenario.
