In short there is no way of knowing by looking at a USB-C cable or socket what it supports because there is a myriad of standards all using the same connector - USB Power Delivery, USB 2.0, 3.0, 3.1, 4.0, Thunderbolt 3, Thunderbolt 4, DisplayPort over USB

You have to usually measure to know what does the cable support and what speeds and or voltages are possible.

Not only that, but it is not possible to make a do-everything USB-C cable.
