Cibb lives on the Western side of the Blue Ridge Mountains at an elevation of close to 1,000 feet. I'm not certain the Noble Muscadine will survive the winters. The climate in Salem is different than Central Virginia and vastly different from Eastern/Coastal Virginia. I still suggest Cab Franc, Pinot Noir, and give Cab Sav a chance. I know Petit Verdot and Merlot grow in Bassett, Virginia at Hamlett Vineyards. I'd give both a try. Double A Vineyards is where I ordered my vines and they are great folks to work with. You get a discount if you order 50 plants of any mixture (grapes, berries, hops, willow). Cibb may not have as much trouble with Powdery Mildew and Downy Mildew by being in a less humid area. Salem gets a lot of rain but rarely gets the oppressive heat and humidity.
Crimson Cabernet is a new variety that some swear is as good as any vinifera, however, the breeders require a minimum of one acre planted, they come potted not dormant, and I've heard they are hard to grow.
Good luck Cibb and start preparing your ground ASAP after you close. I waited until the day before planting to auger holes. I plan to work up the holes earlier next Spring. Also if you have a chance, take some of the Piedmont Virginia Community College classes in viticulture. Most are on Saturdays in the Charlottesville area. You are only a couple hours from C'ville and the classes are not expensive. Many of the commercial vineyards and wineries in Virginia have taken the courses. PVCC has a certificate program but I'm just taking the classes I think I need. I don't think I need tractor safety or tractor repair (been working with tractors for 40 years). Vineyard site selection is also a waste; I own the land and have limited space. Let me know if you have any questions.
I started my vineyard this Spring but have been farming/gardening in Southwest Virginia for 40 years and also for the last 10 in the Northern Neck. I'm an expert in the differences in the climate, soil, and growing conditions between the mountains and Eastern/Northern Virginia.
