Have I went overboard? Any suggestions? Or help? I travel a lot and don't have a lot of time when I am home to setup and configure.
I'm using Cloudron on Linode for some things because I have StarLink and haven't figured out how to connect via internet to my LAN yet. I can use VPN with the router but it seems wonky.

2 Raspberry Pi's with DNS servers

Subdomains with traffic routed through a reverse proxy listening on 80 and 443 (HTTPS everything with certbot SSLs) with a dynamic DNS client updating your DNS provider whenever your IP address changes.
IIRC you can use DNS challenge behind a CGNAT, but you still wouldn't be able to access the system remotely. But you could use Tailscale for that, or Headscale on your VPS. You could also put a wireguard server on your VPS.
