I‘ve recently started using Tailscale for my home setup and I really can‘t recommend it enough. In my opinion it takes a lot of the dangers regarding IT security out of self hosting. Depending on who you ask it is not true self hosting, but I couldn’t care less :)

With Tailscale you can create a VPN for your devices including your phone and even expose services to the outside world with SSL already setup (havent tried that out, yet)

They have guides/tutorials for a lot of stuff (web server, Minecraft).
