I literally spent more than an hour yesterday debugging issues with USB-C cables that I wasn't aware were charging only, and this shows up today... Better late than never, I suppose, and definitely worth my ten quid.

If you can afford it, I'd honestly throw these out. "Charging only" is not a spec-compliant thing in USB-C, and personally I wouldn't want to re-discover which devices do and don't support them every time I just want to quickly grab a cable.
What's less easy to replace are all these damn USB-C devices lacking the UFP-identifying circuitry that only work on USB-A chargers using A-to-C cables...
To be clear, they're not literally "charging only", AIUI they're spec-compliant cables with USB2.0 480Mbps and power delivery, and they're allowed to not have the four SuperSpeed wire pairs. They're still useful for low bandwidth devices (like charging my keyboard/mouse).
Incidentally — I spent an inordinate amount of time searching for USB3.2 cables on Amazon, and the vast majority of cables were actually just USB2.0 cables with PD support, and not actual Full-Featured cables.
Amazon's search is awful and I do not recall a time when it was better. It's probably this way by design, so that it always tends to present a never-ending stream of products to buy.
But over here in the real world where I need a specific sort of USB 3.2 widget: Either the USB 3.2 widget exists, or it does not exist. Presenting pages and pages of not-results that were already explicitly defined as irrelevant do not help a person to spend money. :)
(eBay's advanced search mode seems to still get it close-enough to right when rote specificity is important. I use it all the time to find very particular things.)
Ah, I love these as they're generally much thinner/lighter/more flexible than USB-C 3 cables but still support at least 60W power delivery! Advertising them as USB 3 is a shame, though.
I was trying to figure out slow network speeds one day and I finally swapped an ethernet cable and got full speed.
It turns out some ethernet cables are missing wires - and capped at 100Mbps! Wait what? I didn't even know that was a thing. I don't know where I got the wire, but into the trash it goes.
100 Mbps is sometimes just enough for the job. And it’s easy to see that you only have two pairs instead of four – just look at the connector.
I would recommend getting one of the small cable testers, like the one from Treedix. Gives you all sorts of information very quickly, including resistance levels and capabilities.
