Often when I get a new device I buy a brand new USB-C cable to avoid having to go into this bin of snakes, only to forget to label it and have it fall into the bin itself.
This review is a little old but gets into some detail and mentions most of the common brandnames under which the tester can be found online

Warning: This tester has the capability to damage connected devices, by the user deliberately ignoring and over-riding the device's maximum power request, but only if it's used very carelessly
I went through everything this way when my usb bin overflowed. Now I have a 2.0, and a 3.x bin and it is enough to quicky find what I want.
For power testing I have a Plugable usb c meter, and a Uni-t UT658dual. Neither of these is very smart or standalone though. They are enough to see what voltage is negotiated and how much current is drawn.
Perhaps Google or Bing will be demonstrating something soon if their search engines don't already do this.
