I think that the best option is the F/A-18E due to his multirole tasking and modernity(not so with the F-14 or Harrier), another point of interest would be its carrier ops ,but since already it has been mentioned previously,the chance of embarked operations isn`t very high on the current DCS scenery, by the limitations that have US aircraft carriers to operate in the Black Sea (see Montreux convention, 1936).
In this aspect, my suggestion -as already VincentLaw commented- maybe in the extension of the map or area of operations to south up to covering part of the oriental Mediterranean, thereby opening the way for numerous possibilities of campaign, because then we would dispose of new airbases on Turkey like Incirklik, Batman or Izmir, or the island of Cyprus with Akrotiri to recreate a full conflict on Caucasus, also that this area would be a perfect place of operations for US 6th Fleet CVNs against either caucasus or or a fictional conflict with Syria or Iran.
I know that an extension of this magnitude would be a huge job, but the vast inland regions of Turkey, for example, not requires a high level of detail as it is now Georgia; I limited to only the geographical detail and improve cities, transportation lines and major airbases; after that, the big step would be to recreate the scenes of Syria and Iran, but that's another story ... another dream:megalol:
