One might say that something that could be considered a fairly good indicator of a "good" food-scene would be this: https://www.statista.com/chart/16308/michelin-restaurant-us/ Where SF is no 2 in the country for number of Michelin star restaurants. Again as the first sentence states; one might argue this is not the indicator of a "good" food-scene but I guess we'll have to take what we can in terms of objectivity to try to judge a city on different things, and for food this is at least for high earners, probably a somewhat good indicator.

- You'd have to include SF, San Jose and Oakland together to equal the size of NYC (and much of that SF metro area is single family home suburbs with no one on the street at night)

- Tech workers concentrate in SF proper because there is not much outside of it (yes, there is, but SF is the core)

Just my take, but SF seems to revolve around tech, while finance is big in NYC, it's not the dominating industry like tech is in SF.

you ignore a lot of other industry around the bay and around nyc. Neither Queens nor Fremont are representative of the other areas, neither is Brooklyn or Oakland. Or Berkeley. Or Bronx.
