Im new to the USB-C plugin. Taking a look at anker, it looks like there is usb-c 2.0 , 3.0 , 3.1 , and thunderbolt? If I’m looking for a good “never have to buy again” cable for my new iPad Pro, what version of the USB-C should I be getting? It may one day be used for a display, transfer, etc...just not there yet. Would prefer a 6ft, but if there is only a 3ft, then it is what it is.
