Hi bigmike,
Figtrees are hardy in Zone8, but some protection will always help the fig trees.
For the variety, it all depends on your local weather, so just start with the easier: Brownturkey, Hardy chicago, celeste, Longue d'aout, Dalmatie/white greek family, unknown strains from your neighbors .
What is your dirt ? Full clay ? Full sand ? If so, then dig up a hole of 70cm*70cm*70 cm ( W*L*D) and mix some compost from the nurseries with your local ground.
Check for varmints : moles, voles, rabbits and the list goes on ... Try to keep them out of your orchard.
In Mediterranean countries, Fig tree do handle the sun and love it, so no problem for full sun exposure. You'll just have to water a bit more .
If you fear that full sun is too much, then plant another tree for half-shading purposes.
I myself planted other trees in the garden to act as wind barriers and cold barriers (peartrees, rose plants ,and hedge style bushes ).
You don't need to plant against a structure, but the spot should be sheltered.
Never forget to fertilize and water the tree. If your dirt is not enough draining, you should add compost from the nurseries.
The spot shouldn't have standing water for whatever a reason be it rain ... The water should flow away from the roots of the tree .
