I am in zone 8b and currently have a Golden Delicious and a Crabapple. I have the crabapple because it's such a good variety for cross-pollination. I'd also like to use it for
apple cider vinegar and pectin production once it starts setting fruit.
I am hoping to get an Anna and a Fuji soon. Those are both low-chill hours requirements.
This might be a good resource for you when searching for other low-chill trees:

Edited to add that I found a sprouting seed inside a Pink Lady apple. We planted it, and it's now about 6 inches tall. It'll be a fun experiment to see what becomes of it.
Here is a basic map of US predicted chill hours:
