There is absolutely NO "safety" advantage to using #14 for these loads, regardless of motor start-up.
The breaker protects the wiring, NOT the load, so even if a motor is on a 20A breaker it will not trip any faster or safer on a 15A circuit.
You match the circuit to the load within the scope of the code.
Thing is, it is a code requirement that the ground for most pool equipment be #12 minimum and also be insulated. This precludes any #14 NM or UF cable use.
If you are wiring up pool equipment you should ALREADY be familiar with Art.680 of the NEC. You SHOULD NOT be guessing or winging it as far as this stuff goes.
