I don't have any hard numbers, but I have heard ~85% ICE success rate with out TURN. But you are right, in some cases WebRTC will fail without TURN. Just no one wants to pay to run those servers :) I would love to see TCP hole punching in ICE, but it sounds like it is super hard to get right. Consumer internet does a lot better, lots of those failures come from Government/Military/Medical I bet.

You always need a at least a STUN server and in my experience that 85% isn't remotely true. For example STUN-only never worked from mobile internet (only tested some german providers).

how would TCP hole punching even work? TCP has state and a handshake. UDP doesn't.

  UPnP can be used to setup port forwarding if the NAT gateway is configured correctly.

    sure. I think it's a bit different though. upnp is like some remote control of your fw.
