[@Theorist]I'm a bit confused on the Focuses and it's Human background benefits.

We have to choose between the Cunning or Willpower focuses, but they're included in the benefits for humans?

You actually have to choose between those benefits. You get three advancements; a language or focus costs 1 advancement, but an ability increase costs 2. So yeah, you don't get all of them. xD
