What do I need to know about monitors for office work?

[ExtraSlow]

Hey, just realized I know nothing. What kind of specs or features are important for a monitor for use in an office environment? For the wife's home office, will never see a game. Spreadsheets, maybe some mapping and programming, but 100% stationary shit.
Any eyecare or frame rate or anything important? Resolution matter?

Using some ancient 24" ones.

That's a thread with like ten monitors listed including several that are out of stock or no longer in discount. Reddit confuses me, can you link to a product?
