You need either a reverse proxy running on a vps or something outside your network or a tunnel to your server from something cloudflare that can do the proxy for you without opening any ports.
A reverse proxy will be the public server that relays traffic from the standard ports (80, 443) and then fetches the content from your server on whatever port it has open and then returns it to whatever user requested the page.
Cloudflares tunnel can do the same, but without the need to either open a port nor manage an additional web server. However it needs to be running inside your network to facilitate that connection.
You mentioned already having a cloudflare tunnel that you are using, so I'd stick with that. If you want to not access it over the tunnel and use a fully qualified URL, you will need to host DNS internally with the internal IP address (or use hosts files) while keeping the public DNS entry on cloudflare configured with their tunnel.
Or u-turn nat. You could always do u-turn nat.
