iPXE and USB-C

Yes. I can do a successful "Apple" netboot with all the NICs.

The Dell and the LMP NIC I can't test on an older Macbook since those do not have USB-C ports. The Apple USB-Ethernet and Thunderbolt-Ethernet NICs do work on older machines; however, with the new Macbook I have to add a USB-C to USB-A or a Thunderbolt-3 to Thunderbolt-2 adapter to connect those NICs, so it's not exactly the same setup.
The Dell NIC that I try to use was sold stating it does support PXE booting (that's why we bought it, hoping that this would help).

Build with only basic USB NIC device support:
make bin-x86_64-efi/ecm--ncm.efi DEBUG=xhci

I did that, but to get to the iPXE shell, I need to press esc-B, and the new Macbook doesn't have an esc key (great, really). I usually get around this by using en external USB keyboard, but with this build, the external keyboard is not working - so can't get to the shell.
Apart from that, I can't pxe-boot with any of the NICs with this build either. I can post the output if that helps.

There's no lsusb on Mac... so here is the output of the Mac system profiler:

Seems like the Dell and LMP adapter use exactly the same hardware...
