Thanks for trying to help!

There doesn't seem to be an lspci for Mac, but I'll try to find out about the USB.

Yes, I can build it. I usually use "make bin-x86_64-efi/ipxe.efi". What flags should I add?

As for the USB-C to USB-A Adapter plus a known-working nic - I tried that, and it doesn't work. It will see the nic and tell me that the link is up, but then say "No configuration method found".
Nics that directly plug into the USB-C do not work at all, they're not even seen (tried an LMP and a Dell one, both work fine when booted to Mac).

EDIT: There is definitely no lspci that is running on the current Mac OS (or at least I didn't find one), and unfortunately, Linux is not (yet) running on the new MacBooks, so I can't install that to use lspci either.
The best I can come up with is thus the Apple System Report which shows this about USB:
