What type of motor is this, and how could the power be limited?

Garbage disposal not working: It hums, but the blade spins freely and reset button is not staying engaged
If the unit is not jammed, as you say and the unit hums but does not run, it needs to be replaced.
There is nothing reparable inside these units. You need a new one.

What is the non-specified tolerance of the capacitor of my furnace's inducer motor?
Typically a non-explicitly specified capacitor or resistor is +/- 20%
Out of circuit is the only way to reliably measure the device capacitance, and you're well within tolerance on that.
