True but it really depends on your position on the arc. If you were close to the end of the arc you could, theoretically, catch the bullet in your hand since it's speed is approaching zero.

That depends on the height of the arc. If a bullet is fired at 45 or even 60 degrees, I wouldn't want to be at the other end of the arc.

Zero forward motion is zero forward motion. To talk of a bullet spending it’s energy and stopping forward motion, the angle of flight would only be that which was necessary to expand its energy before touching earth.
