If you're not fussed about amps, one digit is plenty. A-C cables have 3 possible speeds, and C-C cables have 5 possible speeds. And two of those are shared for 6 total, I think. You can keep all 8 separate if that helps remind you that only C-C cables can do monitors and thunderbolt.
There are some weird active cables but the vast majority of USB cables you'd buy today just need a speed rating and a note of whether they're 60 or 240 watts.
