Goldings are flowery, but can have a nice earthy character when used to dry hop. Try Fullers Chiswick bitter on cask as an example.
Styrians, oddly enough i've noticed a difference between whole flower and pellet versions. To me, the whole flower version is quite lemony (try Taylor's Landlord for an example), and the pellet version has a more pronounced citrusy character.
Never used Bobek.
Aurora, try Deuchars IPA.
