Howdy.
As a multidecades resident of zone 8b and lover of home grown fruit, I can make a few suggestions:
1) The
Flordaprince Peach
is a relatively new low chill variety which I have had great success with. I tried other peach varieties over the years but none of them has produced anywhere near as much fruit as this one nor have they endured for any number of years which I'm hopeful this variety will do. Do some research on it and I think you will find, if you like peaches, this one is worth trying. I love mine.
2) Plums are just outstanding in my 8b climate. I do need a pollinator, but my goodness the number of plums produced off of two trees is staggering. We have families who beg for the plums each year to make jelly. They are outstanding and require very little care.
3) Pears are another very low maintenance, highly productive fruit tree in my zone. Honestly, I have two pears trees which are both over 50 years old and which never receive any maintenance and which produce large numbers of fruit each and every year.
I have persimmon, pomegranite, citrus as you mentioned and they are ok but none of them produce the volume of delicious fruit that the above trees provide year after year. Grapes, particularly muscadine varieties, also do extremely well here.
