I feel you. Buying screens is a pain in general. I think I spent two weeks finding a good screen for my graphics stuff that was affordable for a home setup that doesn't throw any money.
I don't think there is anything computer related that is such a jungle of features, upsides and downsides of certain technologies and so on. Panel Type (not just TN, VA and IPS... there's LOADS more subtypes), backlight type, reaction time, grey to grey reaction time, black to white reaction time, energy consumption, resolution, curved and non curved, calibratable yes and no, color depth (many monitors say they use 16bit color but what they actually do is they can UNDERSTAND 16bit but just display it at 8bit anyways), color accuracy, etc.
It was a nightmare. Ended up with this one: https://www.asus.com/de/Monitors/MG279Q/
Granted, I wanted a color accurate IPS panel at 144Hz with low reaction times, and that is hard to find and not cheap. But even if you're less picky about your setup, it's still a major pain in the butt to find something. You also just can't rely on specs that the manufacturers give you. There's hella expensive IPS screens that have IPS glow from hell. No color accuracy on the planet is worth anything if the brightness changes along the edges of the screen.
