Plex is a great product if you want to host your own photos, music, and media such as movies and tv shows. If you aren't a fan of Plex you can try jellyfin. As others have mentioned, proxmox, Unraid, and/or TrueNAS are great if you have unused/extra hardware sitting around. Personally I have a box for Proxmox VM's, and an Unraid server for storage and several docker containers i use regularly. I'm still very cloud dependant for the convenience factor, but this should help give you some direction. There are also communities on reddit like /r/selfhosted and /r/DataHoarder/ that you might want to check out.
