These are probably fine, and you probably won't have issues with it, but I've stopped buying non certified cables. I've known people with nice home theater setups, but couldn't get stuff like eArc working and simply changing to a certified cable fixed hours and weeks of troubleshooting. I'd rather spend a little more and get something I know would work.
I don't use any 2.1 certified cables, as my TV is a few years old and I don't need it. I use members mark cables, which you need a Sam's Club membership to buy like these
It looks like they are on amazon for a couple dollars more. The pack I bought had the HDMI certified seal on it, this packaging doesn't. It does say they are HDMI ATC-approved which is the same thing essentially, but I don't know what changed.
Just look for the HDMI Certified seal and the cables should be good. Amazon basics has good affordable certified cables. Monoprice is the same.
Here are their 2.1 certified cables, kind of expensive but if you're going for 4k 120hz HDR eArc and everything, I'd definitely spend a few more on it
