Look into:

Talescale for an easy but limited option.

Wireguard with a dynamic DNS service for something that provides more flexibility with a little set up.

Don't open a publicly facing port unless it's for an encrypted tunnel. If you don't want to open your computer to a lot of threats. Always use an encrypted tunnel when opening something to the Internet.

Depends on how you want to do it: via a VPN like Tailscale, Cloudflare tunnel, etc.
