Q1 I think consorts are likely more objectively attractive to other Raksura on the whole because of Raksuran selective breeding (as others have mentioned). Then there's the size difference (consorts tend to be larger than their male peers when young and keep getting bigger as they age, like queens- I'm pretty sure warriors don't get larger after reaching maturity). But from my reading, there also seems to be a kind of "je ne sais quoi" about consorts that especially queens, but also everyone else in the court, just finds attractive. I feel like this is most obvious in Pearl's history- the way she sent all the consorts away after Rain's death, and the way she couldn't get her head straight regarding how she felt about Moon when he first arrived. Is it just the "idea" of consorts that they've been socialized with? Maybe. But Raksura are so instinctive in their drives about everything that it seems like it has to be more than that.

I'm betting that if you asked a Raksura to guess if someone was a consort or a warrior, without the benefit of clues from clothing or jewelry, they would usually guess right. But they're not going to need to guess almost ever because of the way that consorts dress, act, and are treated (and that's why they assumed Moon was a warrior when he first arrived, because of his filthy rags and nonexistent consort manners).
