Maybe it's not wise to comment on this while living in Germany and never having been to SF.
But my first thought was: Are they gonna shuttle the kids in and out of the city in order to provide said childcare? Or the staff? How would the staff afford housing in SF on a "normal" salary? Where would they build the required buildings when land costs an arm and a leg?

The city itself is tiny, this is not the metropolitan area of San Francisco, its just the city limits, so yeah people in suburbs will commute into the city to work there, just like most other people working in San Francisco.
There's also great (by American standards) public transit into/through the city. Caltrain and BART can get you into SF quickly from quite a large area nearby.
"by American standards" is doing a lot of lifting. On a scale of 1 to 10 I'd give SF about a 4 compared to cities like Tokyo, Paris, Berlin, London, Amsterdam, Seoul, Singapore, ...
Caltrain is no slouch - punctual, clean, safe, really good wifi, electric.
It also doesn’t get you around the city (and isn’t near any significant number of schools).
It is good for getting in and out, assuming you already have a way of getting to the Caltrain station which isn’t exactly in the center of the city.
I've been to San Francisco twice with work.
The last time was in 2018. I caught a Muni bus, the drive drove past someone at a stop who was in a wheelchair and was signalling to be picked up, another passenger challenged the driver, and the driver shouted something like "I don't want no cripple pee pee-ing on my bus"
The staff in my baby’s London nursery all live outside of London.
Edit: or are very young and live with their parents.
