What age is appropriate for family board games like Catan or Azul?

Publisher recommendations cited in the listings put Catan at 10+ and Azul at 8+, with Catan Junior aimed at 6+. Reddit threads on r/boardgames note that motivated 7- and 8-year-olds can handle standard Catan with parental help, but younger kids usually do better with Catan Junior or a quick card game like Taco Cat Goat Cheese Pizza.
