I don't use options so need feedback.

What default aging period? 1 day? https://github.com/ValueRaider/yfinance-cache#aging
What should happen to an option contract already in cache when it's refetched? Just overwrite?

1 day is best.

Overwrite because there are things that change like price, volume and open interest.
