Does object size and position matter when modelling in Blender?

[Agent Grey]

For instance how big should a sword be in blender and where should the parts be positioned? Should I put the object source at the beginning of the blade or at the middle of the blade?

AFAIK you should be guided by the size of Native parts. You might find this post on the Mount & Blade Modding discord of interest:
