You have a few options. Depending on what your trying to do you could look into Tailscale or ZeroTeir. Basically they create a small VPN that you can join multiple devices to. This won’t open the services to the public internet but it will open the services to whatever devices join your private Tailscale/ZeroTeir network running over the public internet.
Someone already mentioned but CloudFlare Tunnels would be a really good fit as well.
Another option but more expensive and most complex is rent a VPS in the cloud somewhere setup a VPN link between the box and your PC and then route the traffic thought that VPS. All public access will hit your VPS public IP and port numbers and get relayed though that back to your PC.
