Do they allow you to ‘rent’ a static v4 address?
Do you have v6 available and configured?

I personally use WireGuard links to my home and VPS nodes, it’s a bit involved to setup, but you could do the same with Tailscale if you’re not up for the admin overhead.

As for hosting stuff for others to access, I’d put the advertised public interface on a VPS and locate it there, or tunnel it back to your home network if that’s not practical.
