Not related to USB, but flash storage quality in general varies a lot. We have a few hundred Raspberry Pi in operation at customer sites, running 24/7. Back when we started our business we used generic Micro SD (can't remember the brand). They would fail after 2-6 months. This was a big hassle. We have customers all over Germany and would need to ship them a complete RPI as a replacement, as the customers are usually not tech-savvy enough to just replace the SD. We now use SanDisk's "Industrial" Micro SD and haven't had this problem since. Also, reducing writes to the SD is certainly a good idea. Ideally - if you can - mount the system as read only.

Interesting you mention "Industrial" cards as I have been looking at cards in this range after reading quite a few issues with RPIs over the past few months. I have a RPI3 with a SanDisk Extreme, running for 18 months 24/7 with no issues yet. Plenty of re-imaging and high temps. RPI 4 has a SanDisk Ultra, only been running for 3 months 24/7. Now whilst we all should have backups anyway, I really don't want the worry or hassle of restoring backups couple of times a year, I would rather have a card that will last years rather than months. Slightly off topic but I have also been looking at using net boot instead. Not only would it be just as fast as the Micro SD cards but much easier to perform backups locally and offsite.
