Whichever machine has the NAT's external IP assigned to it will accept or refuse the connection, depending on whether they have a server running on that port or not.

The machine that has the NAT's external IP to it is, well, the NAT, by definition. So you admit that the NAT box will act almost exactly like a connection tracking firewall, even if only NAT is enabled.
No, I'm not going to "admit" that, because I know full well that it won't.
It's not like I'm sat here thinking "I know it does block traffic, but I'm going to lie to everyone that it won't". NAT in fact, actually, really and honestly, doesn't block traffic, and I think I've been pretty consistent in saying as much.
You've been consistently wrong, yes. A NAT router box will NOT translate a packet coming from the Internet (so, a packet with a globally routable IPv4 address) arriving on its WAN to the RFC1918 IPv4 address of any box sitting behind it on the LAN side, unless it is arriving on a previously open connection, or on a port the user explicitly asked to be allowed and forwarded - exactly the same behavior of a regular stateful firewall.
