warmbloods are usually taller horses and if you pick one with a short back and strong pasterns it will carry weight.
Otherwise some Thoroughbreds (but you'd have to be very picky there, because there are more so-not-dressage-type TBs out there than there are dressage-type TBs).
I have to admit I am not a fan of Friesians or Andalusians as dressage horses (they are beautiful, just seems to be a bit of an uphill battle to get GOOD dressage out of them). Too much tendency for lack of engagement, suppleness and rhythm, from what I've seen. HOWEVER, they are often taller horses that are solid in build.
Otherwise SOME drafts and draft-crosses CAN be good dressage horses but it is harder to find a real nice sporthorse type.
If you were in Australia I'd point you towards a breeder who consistently produces very nice performance-type draft crosses. They are out there, if the cross is done right.
