I almost don't want to do this, considering you've put a lot of effort into this list and probably don't need someone to throw more choices at you, but this is my go-to for monitor reviews:

Seconding using rtings as a resource. They do in depth testing and follow up longevity tests so you can know the performance instead of taking some person's word for it.
Non of the models I selected are on rtings.com .
Personally I've had a few AOC monitors, and have been pleased with them. Good performance for the price. Caveat that this is personal opinion
AOC U27V4 is too basic for the price . Is Acer CB272K good ?
No idea bud. Never knew anyone who owned an Acer monitor. At best I might have seen one in a shop a decade ago.
I second the AOC. Currently rocking one and it's been great for the price. Sure there are a few spots where the backlight bleeds through around the edge a bit, but that's common at the price point.
Mine's a 34in ultrawide "frameless" gaming monitor I got for ~$420.
I'd avoid LG, their monitor controls suck ass (three button clicks to turn it on and off is unnecessary, power buttons should be a one and done) and I've lost track of how many LG monitors and TV's I've found with complete backlight failure, turning the whole panel blue.
I'm surprised Lenovo haven't been more competitive this year, they have always been my go to for monitors
