There isn't that much more to add. Most of this is based on ingame quest text, item descriptions, and NPC dialogue. The information about Cordelia comes from Gagaruna, the guild receptionist. The information about Ivon Coeurlfist comes from a 2012 Lodestone article. Gamewise, Coeurlfist is also the title given to all monks upon completion of the relic quest.
I wouldn't worry too much about adhering to a single style prescribed by the guild. The NPC dialogue itself states that "The art practiced here is based on her all-encompassing style," in reference to Cordelia and the flexibility of the teachings. Various people and races will adjust accordingly for their differences - an elezen might take advantage of their potentially longer reach, for example, while a lalafell might focus on swift movements and rapid strikes to pressure points.
This is a direct quote from the NPC Erik in the job quests, regarding monks: "...through rigorous training of the mind and body, and with constant invigoration and refinement, one can approach the sublimity of Rhalgr himself. Such is their power of concentration that they are able to master the aether within their bodies and channel it in a manner that grants them immense destructive power."
While other classes might hurl spells or wield magically-enhanced blades and bows, monks channel that aether/chakra into their bodies instead, even manifesting it as elemental attacks with the Fists of Earth/Wind/Fire. This is unarmed combat that will eventually let you solo giants and magitek mecha in Mor Dhona. Precedents exist for a variety of different combat styles and techniques when it comes to magical martial arts, so pick the one that fits your character best.
