This article recommending scrabble letter brands seems sketchy.

Anker offers lovely soft silicone sheathed USB-C cables, in black or white and many lengths. They perform for data and do not get stiff or discolor. Our office specifies these unless TB4+ is required.

Not very sure of heat resistance, but I’ve been very happy with a bunch of LTTStore TrueSpec cables.

this is awesome, I've also been looking for these kinds of cables more than the "braided" cables which are stiff and tend to eventually take some kind of shape and not straighten back

Just beware that an awful lot of "silicone" cabling coming from China is actually overplasticized PVC, particular cabling used in instrument probes. It feels like silicone until it starts getting stiff while at the same time outgassing plasticizer like crazy, or you touch it with a soldering iron or similar. I would expect most or even all of the cat-ran-across-the-keyboard Amazon brands to be overplasticized PVC, not silicone (hint: Use the Knockoff plugin for Chromefox, https://github.com/Shpigford/knockoff, which will warn you for stuff that's sold on Temu West, aka.Amazon, it's warning on almost all of the pseudo-brands listed in the article).

I've also run into way too much cabling that's CCA or even CCS. Garbage on the outside, garbage on the inside.

It’s chubbycables. You’re welcome.
