Sounds like the US lags behind on this, but I'm sure the tradeoffs are made up elsewhere - for example, it looks to me like salaries for equivalent roles in IT are often a little higher in the US.

At my current (UK) employer, I get 30 days vacation, 13 days Scottish public holidays which get added to my vacation (so all paid), and paid sick leave of no more than 3 "instances" in a year. An "instance" could be 1 day, or it could be a month... but if it's longer than 5 working days I need to back it up with a letter from my GP.

The downside is that if I don't use up all that vacation, I lose it - it's not converted to salary (although some companies do this). This is something I'm acutely aware of this year, as I'm struggling to find opportunity to take the remaining 15 days leave I still have to use by Dec 31st.
