I believe only HQ crafting/gathering earns you any points and unless they changed it, it's minimal. GC turn ins are by far the fastest way to earn easy fc points so if you are looking for quick and easy points that is how you do it. Otherwise almost anything you do from leveling up, fates, roulettes, etc all should get you points.

Also the fewer people you have online the more points you get which is great for solo fc.
