Is it safe to open ports 80 and 443 in my home network? (sh.itjust.works)

Hi all, I'm running a small website off of a raspberry pi in my house. I have opened ports 80 and 443 and connected my IP to a domain. I'm pretty confident in my security for my raspberry pi (no password ssh, fail2ban, nginx. Shoutout networkchuck.). However, I am wondering if by exposing my ports to the raspberry pi, I am also exposing those same ports to other devices in my home network, for example, my PC. I'm just a bit unsure if port forwarding to an internal IP would also expose other internal IP's or if it only goes to the pi. If you are able to answer or have any other comments about my setup, I would appreciate your comment. Thanks!

I have my services proxied through nginx and behind cloudflares free tier. That way I don't have to worry about my IP getting exposed and opening myself up to DDOS/DOS attacks, which is a genuine threat if you do things that piss people off (I'm an admin on a popular minecraft server).

You can use Cloudflare Tunnels too, so that you don't even need to port forward.

It’s 2023, the threat is there regardless if you piss anyone off. We’re all commodities that can/will be exploited for capitalistic gain.

I looked into nginx for minecraft, but minecraft doesn't use http headers, so I'd have to open minecraft ports on the router. Would this alleviate that? What's the difference between this setup and using something like a cloudflare tunnel? Obviously, there is still some reliance on Cloudflare.

https://tcpshield.com/ they have a very generous free tier. It requires spigot/bukkit plugins or a velocity plugin (velocity is a Minecraft proxy, think of this as NGINX for minecraft).
