Best variety of fruit tree for beginners in zone 7 Southeast

Would love some suggestions

The majority of fruit trees will grow in Zone 7.  The main restriction will be on tropical plants.  Answering the following questions would help to quickly narrow it down:

1- Do you want fruit, nuts and/or berries?
2- How many do you wish to grow- 1 or more (makes a difference as some are self-fertilizing and some need a second tree).
3- Are there any specific items you would particularly like?

I'd suggest peaches. They grow crazy fast, bare-root whips can fruit in the second year after they are planted, and home grown peaches are so much better than store bought peaches that are picked too early so they can survive transit unblemished. Also, they are usually pruned heavily each year so you'll get lots of practice in that area.

I was thinking going to be several trees  It was wanting to start out slow   Probably a fruit and nut

OK.  That info helps.  Here is what I did to get a quick idea.  I recommend you do the same to get a feel for what your options are.  I started at the nursery starkbros.com.  I really like them, but they are certainly not your only source for trees.  However, the site is good for doing some quick filtering to see what your options are.  You select a category and enter your zip code and they show you what options they have.  From that setup, I came up with the following quick options.  You can click through individual plants to see which ones require pollinators, mature size, how long they need before they produce and other info.

Fruit Trees:

Apples (most require a pollinator, but some are self-pollinating)

Peach

Pear (mixed pollination requirements- some self, some semi-self, some require a partner)

Nectarine

Plum

Apricot (require pollinators)

Persimmon

Figs (generally prefer warmer, but some can deal with this zone)

Nut Trees:

Almond

Hazelnut

Walnut

Chestnut

Pecan

There are other, more unusual trees that might work, but I wouldn't recommend them as a starting point: Jujube, Pawpaw, Quince, Olive, Pomegranate,  

On the net look for and read "fruitbook9".  It is focused on Zone 7 in the southeast. I am growing all of the easiest trees.
