Sheeva isn't Goro's wife. Goro is her husband.
So far, there's notably very few differences across characters based on their stance. Kung Lao's is notable, while Sheeva's, to me at least, is not that great. However, here's a breakdown of the stance change properties of her moves:
Sheeva does not change stance:
Forward Throw: Always makes the opponent get up in a different stance than Sheeva
Back Throw: Always make the opponent get up in the same stance as Sheeva
F3: Changes opponent's stance
DF1: Always makes the opponent get up in a different stance than Sheeva
Sheeva changes stance:
BF3: Always make the opponent get up in the same stance as Sheeva
