Catapult-launch and arrested recovery will still require significant force handling ability whether there's a human meat bag at the controls or not, but not having a human on board allows for a much more efficient aircraft design (though that designed efficiency would lead to variable designs depending on the mission: endurance/ISR, high-speed/high-G attack, or heavy-lift/cargo/tanker, etc).

Catapult launch could probably be much more forceful and frequent without a mounted H1-A Human.

The human tolerance has never really been a limiting factor. As catapult technology and jet technology has gotten better, we've used the additional thrust to launch heavier, more capable aircraft, rather than increasing the initial launch speed.

True, with newer catapult systems linear motor driven instead of steam driven.
