I have tried various methods over the years - XPs, milestones, session-based XPs, training monkey for extras, XP penalties for latecomers...etc
Experience has shown that none of that works for my table. I do not have an attendance issue, my players would play every week if I could manage it, sadly life & wife.
But there are other ways though to reward players (should you wish to):
1) The ability to earn Renown, Faith and/or Sanity Points;
2) Gaining allies, quest leads and more spotlight even expanding networks;
3) Obtaining specialised equipment, vehicles, rare familiars, lore, and magical items;
4) Bonus inspiration points
5) Minor plot points
