I think it may be a heating issue because the problematic ones are in fixtures completely enclosed and in groups of 3. The ones that are by themselves have been totally fine.

Most A19 and B10 style LEDs have been fine.
GU10 and MR16 has been a mixed bag/#### show to the point I've intentionally replaced those styles of fixtures to get away from those bulbs. Some of those bulbs look sketchy AF.
Fuzz's comment and the 10,000 hours comment got me intrigued. Divided by 24, it comes out to about 416 days if never turned off or basically, a little over a year without being turned off. At 4 hours a day, it's 2,500 days, or around 7 years. 15,000 hours would be about the 10 year range at 4 hours a day.
I looked at a few bulbs I purchased and with a stated "10 year bulb/11,000 hours" honestly it seems reasonable to me. I'm at year 4 with these things and I don't think a single one of them have gone bad. Many for sure are used more than 4 hours a day due to WFH, long evenings, kids occasionally turning them on and wandering off without turning them off etc. The 20-25K hour ones are kinda crazy, but I haven't seen too many of those lately.
Even if they don't hit the full 10,000+ life span, I certainly like them better than incandescent and halogen. Lasts way longer, less likely to shatter into glass everywhere in general/disposal/storage room storage, less heat shining a heat ray on your head and you don't have to wait however long to avoid burning your hands to replace the bulb. It's rare they turn on and then fail. They basically just don't turn back on one day and you'll usually notice it when they start flickering.
