Floor plans are static.
People are not.
They move constantly, carrying groceries, laundry, furniture, children, luggage, and sometimes mobility equipment.
Study door swings carefully.
Bathroom doors should not collide with closet doors. Bedroom doors should not block circulation. Refrigerator doors should not trap people.
Hallways should not waste huge amounts of square footage, but they also should not be so narrow that two people cannot pass comfortably.
Pocket and sliding doors can save space, but they need appropriate wall cavities and hardware planning.
Then walk the plan.
Enter from the garage with groceries. Walk from the pool to the bathroom. Carry trash from the kitchen outside. Move a king-size mattress to the bedroom.
If those movements are awkward on paper, they will be awkward in the house.
Circulation is architecture in motion.
