The Future of Nginx: Getting Back to Our Open Source Roots
> But there are many scenarios where being able to extend the HTTP server via Lua is more convenient than writing a plugin I would think?
Well, Caddy is written in Go, so it's only natural to write a plugin in Go. Statically compiled into your binary. We provide a tool called `xcaddy` which is used to produce builds of Caddy with any plugins you need. You just need Go installed on your system to run it, no other dependencies.
The reason why Lua is used for OpenResty is because writing plugins in C is... not fun.
You can absolutely do what you described with an HTTP handler module in Caddy. You'd just wrap the req.Body with a reader that watches the bytes as they're copied through the stream, and when you see the part you want to log, you do that.
We have a replace-response plugin which takes a similar approach, except it manipulates the response as it's being streamed back to the client. https://github.com/caddyserver/replace-response The whole plugin is just one file of Go code.

Nginx Reverse Proxy game hosting
Wireguard gives my service servers their own internal IP for the gateway to reference (nothing fancy done with it, no iptables modifications like you may see on other guides), and I use NGINX for the game server proxying, specifically linuxserver's nginx container. I love Caddy, but even with caddy-l4 I couldn't get it working right for Valheim (and thus UDP), but NGINX worked real quick.

The Future of Nginx: Getting Back to Our Open Source Roots
Well, that's a bit off-topic from the parent comment, which was more about the Caddyfile supporting complex config (versus the underlying JSON config) and not really "complex usecases".
But that said, from a quick Google search... was this an RTMP stream? If so, I suppose you'd want to use https://github.com/mholt/caddy-l4 which is a plugin for Caddy that lets you do TCP-layer things. Caddy's standard distribution just ships an HTTP server (plus TLS and PKI, etc), which is layer-7
You might be able to use caddy-l4's "tee" handler to pipe into multiple "proxy" handlers. But I'm not sure anyone's tried this yet, I had no idea people did this sort of thing. I'd be interested to hear if it does work though.

Brand new to this, have a few questions about DDNS, reverse proxies, etc
If you are only having your services accessible via LAN, HTTPS isn't totally necessary, but I would still recommend it. I think a reverse proxy will be easier than your described method. Just set it to listen to 443 and have all of your other services on random ports being proxied from the reverse proxy. If you want HTTPS from your reverse proxy to your services, most reverse proxies will have this kind of feature. Here is the caddy L4 raw TCP stream module: https://github.com/mholt/caddy-l4

Alternative to SRV record?
I had a similar problem a while back and found this project (Caddy-L4). It had no releases or examples on how to build it so I forked it and added some Docker stuff.

Show HN: Caddy v2.5.0
"Caddy L4" aka "Project Conncept" might be what you're looking for:
https://github.com/mholt/caddy-l4
"Project Conncept is an experimental layer 4 app for Caddy. It facilitates composable handling of raw TCP/UDP connections based on properties of the connection or the beginning of the stream."
