Just as an example of why I hesitate to believe that every race in Eorzea is the same species:
In Forgotten Realms (that's a D&D setting) and, indeed, in the main D&D setting, everything could breed with everything.
Half-Orcs.
Half-Elves
Half-Trolls
Half-Dragons
Half-Giants
Half-Elementals
Half-Kobolds
etc, etc, etc.
None of these races were the same species. Â But a wizard did it!
We even know categorically that Orcs and Draenei in World of Warcraft are not the same species. Â They're not even from the same planet. Â Yet Garona is a half-Orc, half-Draenei. Â Figure that one out.
