Constitution - Contributes to: Maximum Hit Points and Action Point Gain
Charisma - Contributes to: Companion Influence and Recharge Speed
Seriously, the bonuses for each point are so minimal (0.5% and 0.25% respectively) that it really doesn't make much of a difference where you use your points as you're leveling.
Campaign Boons
These I will skip for right now because, again, the bonuses for each point are so minimal and the choices are less relevant for class/role/play-style that pretty much everyone will be choosing the same boons.
Stronghold Boons
Offense - Choose the Power Bonus unless there is another stat in desperate need of a boost.
Defense - Choose the Hit Points Bonus.
Utility - Choose the Healing Potion Bonus if you find yourself using potions often.
