But which usb-c cable is the shitty usb 2.0 speed one that came with your phone and is only good for charging, and which cable is actually a good fast one for sending data, and what kind is that one you bought in an emergency one time because you were travelling and really needed a cable but the box only had Italian on it?

I did the painstaking task of organizing all of my cables last year. I had old VGAs, VGA-DP/HDMI adapters, v1 hdmi cables and a bunch of micro-b (worst form factor imo) usb charging cables. I put all the good cables together and labeled them. For the rest, I collect all of that ewaste in a box along with random lithium batteries and broken small electronics then make a semi annual trip to the local recycling center.
