By saying fluid power systems, I mean hydraulic circuits that make use of liquids power to generate power (kind of the same as steam-powered electricity plants)

Your question is unclear. Do you refer to haydraulic actuation system vs steam/electro-servo actuation systems? Or do you mean to ask about generating electricity?
well it turns out that
pressure is just how much force is applied in area
like if you’re standing on your feet vs tip toeing
you can feel your toes being squished by floor much more
when you lift your heels off the ground
it’s actually not a change in force which is your weight, but higher pressure
applied by floor’s reactive force back to your toes
if we can apply small force in large area like a brake pedal
hydraulic pressure is same throughout the fluid in the closed system (connected by hose)
so reactive force can be great in small area like brakepads
or it can be like a gear/seesaw leverage where torque is same
but you use large gear to turn more distance easily
and smaller gear turns small distance but with higher force
