I would install latest ubuntu server. I use dockge that provides a simple web interface to manage docker compose files, most projects provide a ready to use compose file that you can copy paste. Then you can use tailscale for remote access, expose to the internet via your router, or expose services with Cloudflared tunnel if you have your own domain, I use cloudflare zero trust just to avoid exposing the service directly, requires login via email code.
I got it running, I just didn't get how to do it with podman. Thanks for the hint to use dockge, I'll look it up.
I'm using wire guard with my router for outside access.
Can easily do this with AI now.
