Sure, there are likely many small advantages that add up. For example, 3 flat panels and a few buttons probably weigh less than a metal panel full of dials, allowing for a better payload ratio. That technology wasn't available during the Mercury/Gemini/Shuttle period for any price.

sensors and wiring always weighed more. Of course now the wiring COULD be CANbus or similar in concept instead of individual (heavy) wires. Or move the analog processing and microcontroller to the sensor itself instead of running wires all over the place to a central computer.
Iirc the computers are connected by commodity cat 6e Ethernet.
Do you mean ethernet as the link layer? I ask because I've encountered a number of systems where CAN bus is operated over a cat 6e physical layer.

I can't tell you the answer, but I can definitely say that "cat 6e" is imprecise at best because that's a misnomer rather than an actual standard.
Industry proven technology and easy as heck to replace on-site.
