With the mess that is USB-C and reliability (across brands and power delivery standards) it took me awhile to settle on a cable. So, when I noticed that Flashquark was recommending the WSKEN Mini 2 X-cable for both micro and C, I decided to look for further reviews. Settled on this: https://www.amazon.com/dp/B0782FY8P7

So far so good. Magnet is plenty strong to hold it in place during use and occasional adjustment. Note that it’s a one-way fit and the magnet attraction helps/forces you to connect it the correct way. Also, nicely, the light on the magnet-side of the cable is a soft-white. Not overly bright, but good enough to tell that there is power going through the cable. (And if you don’t like it, just flip it over. My only wish is that they made a L-type style connector.

edit: I can no longer recommend the WSKEN cables. I bought two from Amazon and both burnt out/triggered some power overflow protection and neither work anymore. I’m not enough of an expert to troubleshoot, but they lasted me about 1mo/ea with regular usage on my desk, meaning they were mostly just sitting there and not being disconnected constantly or anything outstanding. I am sad.

These have worked beautifully for me:
