2 140mm's for front intake and 1 for rear exhaust would be good. Adding another 140mm at the bottom or front for intake could help.

the top are 120mm and the bottom ones are 140mm. 4pin PWM is best.

not necessarily, there's cases where you want to go for 3-pin.

I mean, which one is better for airflow and which fan is better for static pressure?

You ALWAYS want to go with PWM unless starting voltages differ between the models. They don't as far as I know.

I need S340. But more Define S'ish

The NF-P14S has better static pressure and the NF-S12B is quieter. 

The 140mm will be better mainly due to it being a 140mm fan unless you don't need as much performance but instead just want a quieter fan.

If you can control the fans via pwm, go with the PWM. If you're using dc, go with FLX.  If you can't control the fan speed at all, go with the lowest available rpm.

PWM can introduce clicking in many fans. Noctuas don't have clicking issues but that isn't the norm.

I think two of the 120mm fans should be enough for intake, and at the back I could have a 140mm. Not sure if I should use one to intake air from the bottom for the GPU.

Listing your specs would help answer that question.
