I like building life clerics that aren't front line combatants, more of a caster cleric than a melee cleric.
I would build a life cleric to be a front liner - but not melee at all. Those are two different axis, they don't have to be related.
Life clerics can get really good AC - they can take some attacks to distribute damage around. Regardless if you are front line or not you want a good CON to prevent losing Concentration, so you have the HPs. Also there are very effective spells that require you to be close, be it from Cure Wounds which scales much better than Healing Word, or Spiritual Guardians if you want to do damage as a caster.
