Help! KV questions for my drone

Faster/more power and not lower the battery life do not go well together. Pick one or the other. That said, you can use more efficient props and/or use slightly larger batteries. My go-to 6mm motors have been the NewBeeDrone Gold motors. https://newbeedrone.com/products/bee-dynamic-rotor-gold-edition-6x15mm-brushed-motor-set
I have been fly 3-blade 31mm props. Lower rotating mass, and more efficient than the stock 4 blade props.
I run 220mah 1S batteries.

More power and longer battery life simply do not go together unless you can significantly improve the system efficiency.
You can't really alter the electrical efficiency of a motor but you can improve prop efficiency. The usual route is less blades, larger diameter and slower rpm which in turn means lower kV motors.
Otherwise more power means a shorter battery duration and in direct proportion or worse!
It will come down to a best compromise that suits you.

I run the Newbeedrone gold motors as well and they work very well.

I replied to another thread you started and linked a video about a fast efficent tiny whoop. It would require some skill to build though. The way the guy manages to get speed as well as efficency and longer flight times is he is using larger propers which by nature are more efficent. As quorneng just said.
