I generalize them for friends who ask and break them down into these variants:
* USB 3.1 (Type-C to Type-C) Charge Only
* USB 3.1 (Type-C to Type-C) Charge and Data @5Gb
* USB 3.1 (Type-C to Type-C) Charge and Data @10Gb
* Thunderbolt 3 (Type-C to Type-C) Charge and Data @20Gb
* Thunderbolt 3 (Type-C to Type-C) Charge and Data @40Gb
I believe 5/20Gb cables are generally rated at 65W and 10/40Gb cables at 100W. But like you've noted there's no standard labeling. So it's hard to find what you're looking for half the time.
It's just easiest to find Thunderbolt 3 cables since those are backwards compatible and if you buy the 40Gb ones you're going to be safer with regard to plugging both your laptop into a charger and your phone.
