Alaska Credit Cards: Are they worth it for me?

Overview

Hi! I live in Seattle and fly to Hawaii 1-2x per year with a friend. I fly to Vegas/California maybe 7x per year (both solo and with a friend). I do usually have at least one checked bag, but will book first if it is only 100-200 more per leg. I'm trying to increase my comfort, so I don't want to do inconvenient stuff to try to get perks (red eye flights, weird days, etc). Also, Alaska lounges would be at best a fallback for me. I'm not sure I understand and can pencil out the perks.
