I started just for funsies, and in the end narrowed it down to just those items that make life better for us. Primarily, I run 2 Technitium DNS (network wide ad blocking), Jellyfin (for media), Home Assistant (to control lights and other devices without internet access), Mealie (recipes), and Ubooquity (books and comics). I have run NextCloud, among other services, but none of them got enough use to make it worth it to continue.
