You should be fine. If you are using port forwarding the inbound traffic on that port should be sent only to the system you have designated. The only way that changes is if the system (rpi in this case) is operating as a reverse proxy. Even then net side should only see the proxy.
The biggest vulnerability would be the system that you are forwarding to, and if that system is a reverse proxy whatever the backend systems are. Make sure everything is fully updated/patched and that you trust the services that you are running and you should be good.
My only comment on your setup would be to make sure you fully understand what you are doing and more importantly, why. Cargo Culting is a bad way to admin. Good questions like yours are a good way to start.
