Sorry, late to the party, lots of excellent suggestions. But would definitely mention Cielo as another option for you.
Location is on the other side of Del Dios Highway from Crosby, the west side of the development goes to RSF schools, but the east side of the development goes to Escondido, so you do have to do your due diligence.
The prices likely higher than you would like to spend, but just throwing it out there as a possible option.
Crosby is probably your best option given you’ll have the option of taking Del Dios to the I-15 as well as the option of going south through Camino Del Sur. Crosby will be going to PUSD schools.
Santaluz is REALLY nice, but again, you’re more south than you should be and you’ll be forced to take Camino Del Norte all the way to the I-15 as Del Dios is gated off. Same goes for Ivy Gates, just too far south.
The Lakes is adjacent to Crosby. Also PUSD schools, you’ll have to check to see if you can drive pass Crosby to get to Del Dios Highway.
If you want to be in the best neighborhoods, these are where you should be concentrating on and still with a reasonable commute. By having the ability to take the Del Dios Highway, you are shaving off 10 minutes off your commute each way.
I do like San Elijo Hills, but it is your classic upper middle master plan community, think 4S Ranch.
Carmel Valley is going to be WAY TOO FAR for Fallbrook.
