USB-C would certainly work, you just need the right (wire) mounting device behind the plug. It's unlikely to be very slim though.

It would be difficult to make a port that works as USB-C with ethernet as an alternate mode. In USB-C there are separate transmit and receive differential pairs, whereas in (gigabit and later) ethernet the pairs are bidirectional.
