Maximum strength improvements are maximized by heavy loads (high % 1RM), whereas vertical jump performance is maximized by lighter loads (~30% 1RM) and power by low-to-moderate loads (40–70% 1RM).
To maximize strength, use heavy loads. To maximize jumping ability, use lighter loads around 30% of your one-rep max. For general power, use loads between 40-70% of your one-rep max. Do not use the same heavy load for all exercises.

maximum strength likely to be maximised with the heaviest loads, vertical jump performance likely to be maximised with relatively light loads (~ 30% 1RM), and power likely to be maximised with low to moderate loads (40–70% 1RM).
