I do agree that there are lots of options to improve an image in post but optimal use of a polarising filter still has it's value, and not just for 'getting it right in camera'. For example, you can reduce haze significantly - this is difficult to achieve in post without also impacting the detail 'behind' the haze. You also get far better exposed images if you can reduce glare, which inevitably blows out if you expose for the rest of the scene - and you can't do anything when there just isn't any detail to play with. And so on...
When taking stills, it really doesn't matter what shutter speed you use, polarising filters can improve the look of the scene (as above) but unless you're going for some creative effect, a still taken at 1/500s would look identical to one taken at 1/60s (assuming identical exposure). The only reason you'd want a lower shutter speed (for a still) is to show motion blur e.g. a still of tail lights streaming along a road. Video is very different, however. We have all become accustomed to seeing a little motion blur from TV and Cinema and when we don't see it, it is jarring. Taking video at, for example, 1/500s would just not look right. You can google it yourself but there is a rule of thumb concerning motion blur, it's called 'the 180 degree shutter rule' and basically it says to get optimal motion blur, your shutter speed should be [one over] twice your frame rate e.g. 25fps = 1/50s. This is where ND filters come in.
Totally agree with comments about WB - just keep it constant and grade in post.
