Firstly, congrats on your purchase, and I'm glad you finally spoke up
Now, onto the brakes.
One should not confuse brake "feel" with brake "power".
Manufacturers spend time engineering the feel into the brake pedal that they think most customers will be happy with. That's right, nothing on a vehicle in this day and age happens just buy chance, everything is engineered to feel like "this", or sound like "this".
So, if you are happy with the braking "power" of your Jeep, and by that I mean if you were to stand on the middle pedal it will stop you in a reasonable distance, which is has to by law, and you simply wish to have a "touchier" feel to the brake pedal, it is quite simple.
Whether you want to actually do it rather than just adapt to the feel over time is another thing altogether
Simply have the brake master cylinder machined/bored to accept a larger diameter piston and seal. This is quite commonly done within the aftermarket.
I would suggest a small diameter increase, approx 30 thousands of an inch would have a marked difference.
Why it does this is simple, for XXX travel of the master cylinder (which is directly attached to your brake pedal), the master cylinder shifts more fluid to the calipers, meaning your brake pads contact the brake rotor earlier in the brake pedal travel, creating a touchier feel.
