I have this setup too and it's pretty smooth. I have multiple services running on my home server, all of them have their own auth, and my home network is behind a shitty NAT. I put Netbird on a remote VPS and it was pretty easy to configure. I have used Tailscale and Nebula (now Defined Networking OSS) in the past, but Netbird was the one that covered all my use cases out of the box and worked flawlessly. If you have services without their own auth, you can put Authelia in front of them. I tried it with a few services and it worked well, but I ended up not using those services so I dropped them from my server.
