user16311: What are the plans for Black when White castles short in the Sicilian dragon? Very broadly speaking I am thinking of two plans.

Go for a King's Indian like kingside attack with e5 played at a suitable time.
Do a6-b5 and generate queenside pressure.

Is one more sound than the other? Or is it just a question of style? What should I be aware of before deciding which one to adopt?

Good news. Black's position is fine; a useful half-open c-file without risks being blow off on the king side. White's short castling is a weaker plan to fight for advantage.
Black has decent chances to take over the board:

Move your rooks to the c-file
Prepare for thematic d5 push
Unblock the g7 dragon bishop

Black has stronger queenside chances while White is not significant better at kingside. I'd be happy to play as Black.

user14202: Pretty much any open Sicilian when both sides have castled King-side Black can seek counter-play against the center by undermining the Knight on c3 with b5-b4 ideas or if allowed Rxc3 exchange sacs. 
Also thematic is trying to play d5.   Bent Larsen said something to the effect that the Sicilian was a positional trick where you trade a wing-pawn for a center pawn, then with 2 center pawns vs one you will be able to eventually take over the center.
I haven't seen games where Black has prospects of a king-side attack in a Dragon where White castled King-side.  Usually White is trying to attack there with f2-f4 etc.
