Instead of Viburnum lentago, consider the more common Georgia natives: Viburnum nudum, Viburnum acerifolium, Viburnum prunifolium, Viburnum rufidulum, Viburnum dentatum.

Siberian pea shrub? I wouldn't.

Consider Wax myrtle (Morella/Myrica cerifera). Good for screening.

Elderberry, Aronia and Hawthorn are good. I've heard Mulberry is good for wildlife. Serviceberry is also good for birds (Amelanchier). Another popular one is Spicebush (Lindera benzoin).

I don't know about SLN - who is that? How far north?

For food, you may like to try growing blueberries. They grow very large in the South. I do not know what "SLN" is, but I recommend buying plants here. If you live in North Georgia try Johnson's fruit. They are not cheap, but they are good and you will have good plants that will grow and feed you well.
Nanking Cherry (I have bought some on eBay very inexpensively as tiny plants, they grow fairly quickly).
Elderberry
Aronia: try Viking, it's 6' tall where as nero is only 4' tall
Serviceberry
mulberry are good however they are weedy as all get out and you could end up with a forest that you and your neighbors do not want.
Chicksaw and American plums will do you very well
Flowering quince shrubs - they can get to 10' tall and will fruit
Goumi
Hazelnuts
Washington and Cockspur Hawthorn (although my washington hawthorn died very quickly as bugs LOVED it)
pineapple guava (depending on where you live)
Pomegranite (depending on where you live)
If you are in the N. GA mountains I think you could probably do very fine with currant bushes too

SLN is likely St. Lawrence Nurseries ( http://www.sln.potsdam.ny.us/ ). That company has an excellent reputation/rating on Garden Watchdog.

"mulberry are good however they are weedy as all get out and you could end up with a forest that you and your neighbors do not want."

That depends on what type of mulberry we're talking about. Some should be fine and not become a problem. You definitely would want to stay away from Morus alba.

Big thanks for the help.

SLN's mulberry(I'm remembering 'Northrup' or some such variety name) is a Russian/Tatarian-type M.alba - don't bother; any GA native M.rubra will be much better - as would 'quality' M.alba selections, like Pakistan, Shangri-La, etc.

Hawthorn? If you're going to plant a hawthorn for fruit production, I'd be opting for a a good Southern mayhaw selection or two or three.
