It is surprising how much more affordable 4k displays are. I was stuck finding a suitable display for my macbook being used to the 5k iMac, and ended up with the 32 inch samsung m8, which is one third what apple charges for the 5k studio display. I find myself liking it more in practice than the 5k imac, because while it is a bit less crisp, the colors once properly set up are equally nice and the size is luxurious.
It depends. If text contrast is a priority, VA provides better blacks. Personally I also can’t stand IPS glow and rather live with the VA off-axis gamma shift. OTOH, my favorite VA monitor is now 15 years old and there is no current replacement with the same picture quality. I’m hoping for more OLED monitors coming out.
IPS black imho better choice (I own one). VA looks very very bad with dark themes in IDE. Also, I do not know any Eyesafe certified VA's. I am sensitive to blue light and my eyes love Eyesafe certified panels.
IPS panels have the best color accuracy and viewing angles. VA can produce the best blacks but pixels are slow to change. TN are the cheapest and historically have the best refresh rates.
