Nevertheless, I'm still unsure what exactly this cap's purpose is.
AIR, they are often referred to as 'motor-start caps' or 'motor-run
caps' but why are they needed?

Typical motors don't have to torque to start turning on their own.
The start winding in series with the start capacitor provides the
torque to start the motor.
There's a switch to disconnect the capacitor after the motor comes
up to speed.
