I think you are mostly lucky in that you only need a limited subset of the full functionality. You were lucky with video, you probably don't need Thunderbolt, your charging needs are modest, and you don't care about peculiarities like USB 3.1 Gen 2 speeds. In that scenario things will usually work fine, assuming you don't save on cables. But it's enough to just read the cable reviews to learn that things are not always fine. Also, one thing which cannot be blamed on "crappy cables" is that the presence of a USB-C port on a computer does not mean much at all, because in general one has no idea what can be connected to it.
