Well, depends on where you're moving to San Diego. San Diego proper, or around San Diego? We have SO many microclimates out here. If you're right, RIGHT on the coast, you may not have the fruit set you would have if you're a little bit more inland. Cameo is widely adapable to our S. California climates. Probably on par with Fuji for chill hours. A bit more than, say, Anna, Golden Dorsett, Pink Lady or Beverly Hills, but it should perform just fine for you. Welcome to San Diego county! And yes, many, many apple varieties will do well here. Patty S.

Depends.... many people just walk by these things. I've seen loquats falling and rotting for the past 3-4 weeks. No one is eating them! I see fallen citrus/plums it's pretty sick. Some kind of market failure because people buy these things at the store yet they are rotting all around the neighborhood. I think OP will be okay. If he turns some passerby onto fresh fruit, that's a good thing.

Check out the TESTIMONY in these forums of the power of organic materials to tame/ammend clay soils. I don't recall what water source that the Olivenhein German/Swiss settlers had when they planted olive trees ... but do recall that dry-farming [beans] was used for years. You didn't mention what water source you have [well?] and that will make a difference in what kinds of trees/shrubs will thrive. So, may I suggest that you start with truck loads of [FREE]tree trimmings to create compost piles and to mulch? Ditto for FREE horse manure [lots of horse owners in RSF will be happy to contribute.] Check out the drainage patterns on your lot ... including whatever elevation/terrain changes you plan on. Also the prevailing wind patterns will help in tree placement. Also, check for fire safety in placing your trees. My insurance carrier canceled me because I wouldn't trim my Deodar 30 ft up from the ground. With a history of wild fires, insurance companies are getting antsy. As for what trees to select .... why not check out QUAIL GARDENS .. they will have both exotics and natives to see how large they grow and under what conditions they thrive. My mother has a huge 50 year old Torrey Pine tree in her yard. [Encinitas] It is drought tolerant .. to a point. Certainly striking. I had 50 ft. Cherimoya trees in my Vista yard and have one of equal size in my Escondido yard. Very attractive trees and I think will fit into your zone. Though not that large, I hope you will find space for Ceanothis Here is a link that might be useful: San Diego Native Plant Society

Nurseries in San Diego with Asian veggies and rare fruit trees. In my opinion one of the best is the Bonita Creek Nursery, they have a huge selection! http://www.bonitafruittrees.com David, the owner, is GREAT and the fruit is super. They have Avocado, Cherimoya, Cherry, Sapote, Guava, Figs, Mangos, Berries and many other trees. The nursery is in Bonita, just 15 minutes from down town San Diego by car. Have fun!
