If you just want to know what wires sets you have in your USB cables you can get the Gikfun "USB Cable Tester - Fast Check for Type-C/Lightning/RJ45 | Tests Charging Data Transfer | Continuity Check Quick Cable Sorting"

It's only $14.

It even offers test pads you can use to test the cable with a much more expensive multimeter.
