This one will test up to 240w, so you can be sure you’re getting the best that’s currently possible:

Seems like there should exist some kind of specialized cable tester. There is this one, but it presumes background knowledge:

Seems like there should be something even simpler that might boil all the information down to the critical distinctions for the average consumer. Like maybe this one, which appears to consider both PD and QC?

Edit: sorry for these absurdly long amazon links. There used to be a way to get a shorter link, but I don’t see it on their webpage anymore.
