I use CNAME records and it works on everything except Windows, where it works sometimes.

Basically, CNAME record from service.myserver.com to myserver.internal on a public DNS server, A record from myserver.internal to 1.2.3.4 on private DNS server.

I think I could maybe get it working on Windows too by tweaking the TTLs. Currently both DNS servers are automatically setting the TTL and I think Windows freaks out about that.

This seems like a good technique. What DNS software do you use?

I just use the one built into my UniFi router. Public DNS side is Cloudflare, which allows easy DNS validation for Let's Encrypt.
