There was a thread on this not too long ago, just for reference. 
To recap my point from there, we know both non-magical and magical healing exist in the world, and they can be performed without any significant consequences for the caster (improper "conjury," as in Selphie's case, notwithstanding). One can easily come up with lore-friendly reasons why Esuna can't cure a plague, for instance; I go with "conjury repairs 'patterns' to their natural state," which means it alleviates symptoms of illness (by repairing the target's pattern) but doesn't expunge the causative agent. Conversely, curative magic can trivially patch up battle trauma shortly after it's caused, since it's just a matter of the channeled Aether repairing the underlying pattern to how it "should" be. However, a historical injury (scars, a bone that healed improperly, a missing eye, and the like) can't be healed because the target's pattern has changed due to the natural healing process.
Ultimately, though, the limits that magical healing has are dependent on the narrative and the one primary lore restriction, which is that, in general, the dead can't be raised. If the person being healed wants to be fully healed, then great; if not, then that's fine too. Either approach is fine so long as powerposing doesn't come into play on either side and both people agree to the result.
