Westview is good high school. There is a neglible amount of difference between elementary school in Carmel Valley, RB, 4s, Poway, Carlsbad. But it’s.still way too early to think about high school or even middle school.
I anticipate since you are only going to be trying out San Diego right now, if you do decide to stay, you will probably move again anyway.
I would ask other people as well who live in some of these other areas who can give you more details about those schools.
Since you will be working from home, you have a lot of flexibility where you can live.
If you are concerned about whether school districts will allow late enrollment, one thing to do is go to Zillow and look up a house in a given area. The listing will give you the school they belong to and you can Google the school and get the contact info for the school district to call to find out about their enrollment process.
