The elementals being so tied to the Shroud seems like it's a pretty vital piece of information in understanding them. Nature is everywhere, but they're not, and they're not even apparently necessary for a region being a flourishing wilderness- the jungles south of Wineport are doing just fine, without any elementals needed to protect them.
I think it's not necessarily a good idea to assume that they would be everywhere, or that they're all-powerful. Their power is clearly connected to the Shroud, not anywhere else. And in regards to Morys not being allowed to leave, it sounds less like the power of the elementals reaches beyond the Shroud, but more that because he had something tying himself to it, the elementals were able to reach out to him specifically to drag him back to their realm before he could get too far.
There's nothing equivalent to them elsewhere in Eorzea or Hydaelyn in terms of power or role. No "Sandwrath" or the ocean rising up to punish anybody who threatens Vylbrand- hell, even the neighboring Mor Dhona didn't have elementals acting in this fashion, and it was a forest region!
White Mages, Succor, elementals, Padjal, and the Black Shroud- all of these things are pieces of a puzzle, and specifically pieces that all fit into one particular region of the map. Speculating that there may be elementals elsewhere in the world is fruitless, because if there are, they're even less powerful than the post-Calamity elementals of the Shroud. This is what there not being any equivalent force to the Greenwrath elsewhere suggests- or, alternatively, if we're to believe for a moment that there are elementals elsewhere, that the elementals in the Shroud are just territorial assholes in comparison to the elementals everywhere else, and are the only ones that mark threats for exile and death if they're displeased.

My character is currently pondering whether eliminating or otherwise neutralizing the elementals of the Shroud would be a net positive for the world. In her mind, if the elementals are interfering with the learning of magicks that could potentially save Eorzea from Primals and the Garleans (as she's heard in rumour), they've
To the OP's question, I think Sounsyy has covered most of the viable approaches. I personally think the most plausible is "taught by another White Mage for some reason;" I would caution against going with playing a Padjal or an elemental, because for many RPers, that's a bridge too far as you're asking them to accept playing something that can't be played in game. Another possible option is "uncovered the keys to White Magic yourself," though I believe that strays away from lore since the elementals, according to those who've done more of the WHM quest line than I, directly control access to the underlying power source.
