My father left me a little bit of money. What should I do with it.?

Not pushing back on that advice- but i believe there are savings accounts now with banks like Ally bank and the like that are paying around 5% interest.. what would be the advantage of a short term CD as opposed to a high yield savings account ? Im speaking of 2024, not 2 or 3 yrs ago when interest rates were lower, or about 2026 or 2027 which might be the same case .
I was thinking very short term - like 90 day

ETA- just checked. A 90 day CD can earn average of 5.66, up to 6%
