I was going to ask, but I just looked it up: it looks as if USB-4 has enough bandwidth to drive dual 4k monitors at 120Hz (and docks exist that support this).
USB4 uses something called DP-Alt where it’s actually DisplayPort over USB exactly what you’re looking for. I have a portable USB-C monitor that runs powered and video over a single connection
