I'm not into video, mostly Photo. Which would the PolarPro Filters do you suggest? Thanks in advance.

ND filters are mainly to control motion blur in video and are almost pointless for stills. Polarised filters will add a slightly different effect to the blues in the image and reflective surfaces but are difficult to align to the sun due to the yaw of the drone turning direction constantly during flight. I don't use ND's when the main purpose of my flight plan is purely to take stills.
