Whisk the all-purpose flour, whole-wheat flour, baking powder, baking soda, cinnamon and salt in a medium bowl. Beat the butter and coconut oil in a large bowl with a mixer on medium-high speed until smooth, about 2 minutes. Add the granulated sugar and brown sugar and beat until smooth and fluffy, about 3 minutes. Beat in the eggs one at a time, then beat in the vanilla. Reduce the mixer speed to low and beat in the flour mixture until just combined. Beat in the oats, coconut, pepitas, sunflower seeds, flax seeds, walnuts and cranberries. Cover the dough with plastic wrap and refrigerate until firm, at least 2 hours.
Position racks in the upper and lower thirds of the oven; preheat to 350 degrees F. Line 2 baking sheets with parchment paper. Roll the dough into balls (about 2 tablespoons each) and arrange 2 inches apart on the prepared baking sheets. Bake, switching the pans halfway through, until the cookies are golden and dry around the edges, 18 to 20 minutes. Let cool 5 minutes on the baking sheets, then transfer to racks to cool completely.
