Of course, Regen and Shields apply as well as designations for healers, but let's focus on the other aspect right now.
Sustain Healers either through action or automatically continuously heal their party members, always giving them heals indirectly thus making the burden of keeping them alive less stressful overall. Sage does this with a combination of its shields and its offense imparting minor healing to the primary target of its Kardia ability. While Scholars Fairy regularly/automatically cast healing spells on party members who seem to need it the most, as well as the scholar itself buffering members with shields. This allows both jobs to regularly assault enemies with dps. There downsides, in my opinion, is their limited (by resources), ability to pinch heal. Yes using their job's limited resource gauges they can momentarily give out strong instant heals, they cannot, however, sustain it for too long.
Pinch Healers, the white mage, and AST excel just that, healing in a pinch, both have potent healing abilities that can take a party member from low to near full hp relatively quickly, though the White Mage does it way better than AST. Thanks to AST's Lightspeed she can dump Benefic II instantly multiple times over the duration of Lightspeed this is her path to Pinch healing supremacy but Lightspeed has a long cooldown, and if mismanaged really limits her ability to be a pinch healer. In a similar vein, WM has Presence of Mind which increase the speed they can dump out a lot of GCD healing like AST but not instantly, still, their OCGDs for healing outnumber AST and thus these are her path to healing supremacy.
Now that I think about it, Pinch could probably better be described as Burst healing.
So yeah, those are the design underlyings of the current healer role in my opinion.
