This may be obvious but since the packing fraction for both hexagonal close packed and face centered cubic is the same (74% i believe) why is HCP more common in elemental compositions?
Why is HCP more common than FCC in elemental compositions?

Well, I don't really know, but I noticed that a lot of the Lanthanoids and Actinoids are HCP, and if you exclude those two sections, the number of HCP and FCC elements are almost the same.
This is the sort of question that I doubt there is an intuitive answer to...it's all quantum mechanics!
