I came up with a color code based on the wiring: Red for Power Only, Blue for USB 2.0, Green for USB 3 (the ones with the extra pairs connected). I use paint pens to mark every cable I come across with this code. Generally speaking, only the Green ones have special PD emarker chips.
It doesn't cover every possible configuration, but it's good enough for when I'm like "I need a USB cable" vs "I need a good USB cable"
