What does it mean for reactive power to be delivered / consumed?

The true benefit is when an inductor AND a capacitor are in the circuit. Leading capacitive reactive power is opposite in polarity to lagging inductive reactive power. The capacitor supplies power to the inductor decreasing the reactive power the source has to provide. The basis for power factor correction. Select RLC in the reference.
