PVE Hunting guide?

Does anyone have, or are interested in creating a PVE guide to drops? Basically “best place” to farm for players to get a better understanding of planetary difficulty levels and their effects on loot tables.

As a Federation player living on the HQ, I seem to be able to get Yellow Alien Containers and Mining Cores, regularly. But I have no idea where to get my factional Alien Containers as drops. Does a lvl 5 PVE planet have those as potential drops?
Just a thought for a guide. I certainly am not well traveled enough to do it, or I would submit it.
