You’re basically trading energy to move higher volume of air. The fan can move smaller amount of air at higher speed, but larger amount at a gentle breeze feels nicer and helps with circulating the air in the room better.
You could achieve it by taking that exact motor and slapping a bigger fan onto it, but that looks less cool and probably produces more noise? Maybe there’s some efficiency differences if the motor is better at spinning fast, but as a spherical cow in vacuum it should be similar.
It’s cheaper to make electric motor spin fast with low torque than slow with high torque, a ceiling fan of the same cfm needs a bigger motor than a standing fan.

I would counter that a small fan spinning at high rpm makes more (annoying) noise than a large fan spinning at a lower rpm.
But due to it being hidden maybe it can be isolated easier?
