These are all great suggestions. McClelland Navy Cavendish from their Matured Virginia line is one of my favorites. Don't let "cavendish" throw you off; it's a Virginia flake. It's mild to medium in strength, but with a deep rich flavor that's got a malty, sweet, bready thing going on.
I've also been really enjoying a couple of VaPerOr blends like Low Country's Waccamaw and GLP Temple Bar. Both are complex and rich in flavor, but not too strong
