Honestly, I think there's 3 factors that can be used to approximate - but needing real world testing to validate, yes - the effectiveness of a fan in any use case:

Intake: Stream Coherence>CFM>Static pressure. Stream coherence is about how well it will actually push a coherent stream of output over a PC's guts; less CFM but more coherence will outperform the opposite significantly. You need enough static pressure to deal with intake filters but not more then that. The AN140 has very good metrics to sound in the first two - tbh, I don't think the style of impeller InWin uses there scales down well compared to the AN120, as at the same startup speed and thus comparible noise the 120 gets literally half the CFM.

Radiator: Static Pressure>CFM>Coherence - you need to shove it through; shoving more through can help, but it needs to get through. Coherence is useful in a pull config because it helps it cool the rest of the rig, but of no importance to a puller with effectively the big damn stator in the way.

Air cooler: CFM/Static Pressure/Coherence: You want a lot through at enough pressure to get it through but not more then that; less statored then a rad, but the same caveats apply, otherwise incoherent but high volume air pumping is good here.

Exhaust: CFM/Coherence/Static Pressure: get the air out of the case in large quantities; a coherent stream may be useful here as it would get the hot air far away from the rig to reduce the rate it inhales its own exhaust. Some static pressure is useful for penetrating the lesser filters one should install to protect the rig against infiltration by ambient dust when powered down, but not that much.
