All questions have a "relative to" part of it. So I would deep deeper with more questions to you before I could answer some of questions.
The provided websites will give you guidance regarding crime and school scores. As for commute where are you commuting to and at what time of day each way. The commute from South to North via 85, 87, 280 and 101 is very popular in the morning. Right now that the schools are out, including the colleges the commute is less. Depending on where you hope on and blend you may hit metering lights. If you are a commuter you will have the benefit of a passenger to get into the commuter lanes.
As for schools, most people seem to focus on the school scores. I like to open your mind to focus on the needs of your children. Each school has a focus, your needs may be very different than the next family. Are your children into the Arts? Science? Math? Sports? Any special needs? What ages are they? Do you need day care on sight or close by?
The advice to drive around the neighborhood is very sound. The best time is during your typical commute and when children and are going to and leaving school, plus nights and weekends. A quiet neighborhood can turn into a sport's or commuter parking lot.
All the best to you.
