Problem with home labbing

I have a Docker box with Portainer where you can have containers running different apps. And that is the problem. What do I put on. Pi-Hole was a fail. But what do I put on it: Immich, Jellyfin, Bitwarden or something that runs video game roms? When I first decided to this I was worried that I would be in this predicament. I have a NAS box for years and it works great storing my videos, music, pictures, documents and software. Plus do I want to give it access to the outside with a VPN or reverse proxy. I will keep at it and hope to find some that satisfy my needs.
