Interesting request because so far I have also not found a really good everyday standing, walking pose collection other than the pin up, dynamic, model posing etc that you mention.
Everyday standing poses sound so simple to do but I think in reality they are some of the most difficult poses to get right and some help from very experienced artists would be great.
I have also tried partial body pose sets that are on offer at Rosity.  Perhaps the answer is to find photographs of poses that are near to what you need such as the ones found in news papers, magazines, movie clips etc. and take it from there.
But I agree with your quest.

The ones I that might mention are the Schlabber partial fantasy packs these I find useful but to a point.
