Two things to note relating to that last:
1) You need more than 1G of thrust to launch vertically, and even more to launch directly into the air from a standing start at a lower angle than that. Carrier aircraft launch with at most a modest incline. Thus they need to benefit from aerodynamic lift.
1b) If you rely on aerodynamic control surfaces you have no flight control at very low airspeeds.

2) Jet engines may not achieve their best thrust at rest. Though the thrust stats you see for them seem likely to come from ground testing.
