A few additional observations.
Bards through level 5 only get the most rudimentary healing spells.
Cure Wounds, Healing Word, Lesser Restoration. The Glamor Bard helps as it's an amazing source of temp hp.
Clerics get a lot more.
Cure Wounds, Healing Word, Lesser Restoration, Aid, Prayer of Healing, Mass Healing Word, Revivify, Remove Curse.
The more I think about it the more I think that a good healer is more than someone who can supply hp and temp hp in battle. Therefore, even though I think bards are great and very competitive in the in combat hp/temp hp department I am going to go Cleric.
I am choosing life cleric over Order Cleric. I'm going to go with the skilled option as there are already 2 party members I know of that chose the equipment background and so only have 2 proficient skills each.
