I use Nextcloud setup fory whole family, about a dozen all together. I even sprang for the DavX5 plugin for several people so we can share calendars and contacts as well as files and notes. We backup photos from our phones using the Nextcloud app. Several of us use it as a backend for KeePass.
We use Jellyfin for streaming; movies, tv, music videos and music. It is the backend storage and library organizer for four Kodi boxes, five browsers, several phones and tablets and a couple of Roku’s. It works like a champ, even with the occasional library re-sync.
It is designed for one user, multi-channel push notifications. Like Firebase Messaging but self-hosted. You can use Markdown when composing the messages and do about whatever you want.
