Can someone please explain to me, a casual home user, why it's dangerous to expose my NAS login page to the internet?... (alien.top)

...without snark or jumping down my throat. I genuinely want to know why it's so unsafe.

I'm running a Synology DS920+, with my DSM login exposed through a Cloudflare tunnel. I have 2FA enabled, Synology firewall enabled with these rules in place. I also have this IP blocklist enabled.

After all of this, how would someone be able to break in via the DSM login?

Sounds like you did a decent job. Why would you connect the Proxmox host to the VPN? Typically you’ll route certain local addresses (or whole subnets) via chain forwarding. That way, when you connect to the VPN it’s as if you’re on the local network. The way you’re describing it, you would need to know it’s VPN IP which is usually dynamic. And you don’t typically want VPN clients to be able to access each other - just the local network. It really all depends how you set everything up.
