If I throw it up - why doesn't it stay still while I move at 500mph? Is this the pressurized cabin? If so, what would happen in an unpressurized cabin?

Not due to pressure.
When you are about to throw the ball( ball is still in your hand),
it has the velocity same as you have which is same as the plane.
Thus unless the plane accelerates suddenly of takes a sudden turn , the ball always comes back to you.
Simply you can say since the ball has the same speed as u,it travels the same distance while its thrown up as much as you have and then falls at the same location.
Air pressure has nothing to do with this effect.

The ball is moving at the same speed as the airplane. Because the fuselage prevents any air resistance (friction) ... the ball will stay in motion at the speed of the plane. The ball will only move forward or backwards in response the the acceleration/deceleration of the plane.
The up and down movement of the ball is controlled by gravity and would only be affected by the plane if the plane went up or down. If the plane goes down at the same speed as someone in free fall, then you will have the sensation of weightlessness.

Everything in the plane is moving at 500 mph, so when a passenger throws the ball straight up it continues to move forward relative to the ground (inertia) while there is no relative motion between the ball and the plane or the passenger.

You could think of yourself, the plane and the ball not moving at all, and the earth and everything on it is zooming back at 500mph. Your question is similar to asking why does a suspended ball on earth not move since earth is whizzing through space at million of mph.

your thinking about gravity. in an unpressurized cabin, you would be dead. you would have to be higher up in space for it to stay still.

Check out Newton's 1st law of motion, and it makes sense.
1st. Law: I. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.

It does move, but at the same speed as you. So it does not move relative to you.
