Most of the commercial nosecones are blunt instead of pointed. Is this
for safety, ease of manufacturing, or is there an aerodynamic reason?

At transsonic and supersonic speeds, you want a pointed tip. There ogives and
cones are better than the parabolic and elliptical shapes.
Most model rockets, LMR, and HPR are quite subsonic, thus rounded. Sharp points
are easilly damaged, and probably somewhat harder to mold well.
