Question on talking about food

Is there a difference between sabroso/delicioso/apetitoso or are they all pretty much just different ways to say tasty/delicious/appetizing/yummy?

And for these couple of phrases, am I saying them correctly:

If someone asked me if I want X for lunch or something, could I say "Que suena sabroso" to mean that sounds good/tasty? And does sabroso ending in an O or an A depend on what that food is or is it always an O in that phrase?

Would "La comida cocinaste huele deliciosa" be a good/correct way to say "the food you cooked smells delicious" if for instance I was at the dinner table and was handed a plate?
