That's an extreme example, and in the worst case scenario there are plenty of good private schools to send your children. But choosing to live in SF comes with such a set of pros and cons that many parents of school-age children who have a choice choose to live outside of it.

What’s really hard to stop are the doctors and lawyers who just send their kids to private schools and vote against everything.

Presumably the good schools got good because they're in rich neighborhoods where the parents pour time and money into the schools. If their kids are going to a wider variety of schools now, the rich parents will have incentive to make all the schools good.
- more expensive: pre-K is now universally funded by local government and the public schooling system has decent pathways. General living expenses are more expensive, but not so much so if you're comparing with any of the NYC suburbs with decent schools.
- less safe: NYC has become, on a per-capita basis, one of the safest cities in the country, and certainly the safest large one. In general, a massive amount of "eyes on the street" helps keep crime down, whereas in the suburbs being outside alone is not uncommon.
- less space: in terms of living area and backyard, strictly speaking, yes. But I lived fine in a two-bedroom apartment with my parents. There are also houses with modest front and backyards within the city limits, and we moved to one of those with the addition of another child. Do you need 3000 sq ft and an acre of land to raise a child?
As far as outside, the city offers a lot of playgrounds and parks with other people in it. And then as you get older and outgrow the playground, the constant variety of things really helps with boredom, and many attractions like the museums are even free for residents. And the cherry on top is that the mass transit system allows children to travel without a chaperone of legal driving age, so parents don't have to pick between chauffeuring children around or keeping them at home.
Queens is 2.3M people, but they're mostly in low-rise, <5 story apartments and houses of various sizes. Fresh Meadows, NY is hardly suffocating levels of density, and yet this kind of neighborhood is simply not available in most metropolitan areas. https://www.google.com/maps/@40.7337074,-73.7813407,3a,75y,3...
I require space, comfort, and convenience for family, not eatery and nightlife variety. Proximity to interstates and international airports is also desirable though for work and vacation travel.
As a late-20s person living in the city, this is a thing I've been pondering. I grew up in typical suburban sprawl living "close" to school, soccer practice and friend's houses... but "close" still meant entirely dependent on my parents for rides to each place (less the 5-10 children my age within a 1-mile walk). It was a huge time sink for the family, and having to be driven everywhere felt isolating as a child (i.e. can't hang out because mom is too busy to drive me). Not every urban neighborhood is inherently walkable, but many cities have inner ring suburbs (usually within city limits) where all of those amenities are at most a 20 minute walk away. Would this type of neighborhood be livable with your requirements?
My partner is a stay at home mom who wouldn’t mind providing daily transportation, and after a certain age we’ll just provide electric scooters and bikes to our kids before they’re old enough to drive.
That said DC is a small place surrounded by some significantly urbanized parts of Maryland and Virginia (eg Silver Spring, Alexandria, and many of the communities with metro stops).
DC, Philly, Baltimore, Cleveland... all the same story. Even in gentrifying and resurgent neighborhoods, parents with the means to do so leave as soon as their kids get to school age or enroll them in extremely expensive private schools. Some might try charter schools or selective magnet schools, but the local neighborhood school in your typical big city is typically a hard "no go".
