Japanese maples can be grown in zone 10 coastal southern California but that area lacks the humidity that Florida typically produces. With only the rare exception, JM's produce the smallest types of maples or those most likely to be suited for a patio container. It really doesn't matter which cultivar you pick - none will be more tolerant of high summer/fall humidity than another and the light conditions would seem to be appropriate for any as well. FWIW, higher humdity levels would be likely to produce a lot of foliar fungal problems

I'd be skeptical about expecting much in the way of fall color.....much of that has to do with cold temps concentrating sugars and pigments and that is unlikely to happen for you. Doesn't much in SoCal, anyway.

It would be enough for the tree to just survive. I can give up the fall coloring. I just want to have a tree that is happy and thriving. If it can be grown in zone 10 in California, I'm assuming that if the humidity is the only difference, I might be able to give this shot.

Japanese maples LOVE humidity.
They grow in zone 8, South Carolina, very good, but only
specific types.(not all JM grow in zone 8).
Don't grow it in zone 10.
Get into something you can grow in zone 10.
It's the heat and duration of winter temps.
