The variety in abilities comes with what cross class skills you pick, but again I think there is definitely a best set of skills/rotation per class.
This is pretty much the case. There is, for the most part, a "best in slot" for each class, both when it comes to gear and cross-class skills. FFXIV doesn't really go out of its way to try to make characters different, only the people who play them.
In some sense, that actually makes it more focused on player skill - when everyone has the same gear, the people who are better at making use of the tools available to them will perform better. On the other hand, it leaves a little less variety for those who like to play around with variations.
Also far as support classes go, the only ones that are really "pure" support are the healers - White Mage and Scholar. White Mage is the "straightforward but powerful" healer with straightforward big heals; Scholar is the "versatile" healer with a shield and HoT focus - they also have a pet for further utility.
Bards have a couple of songs they can play to buff their group, but they're primarily a DPS class first, support second. Most of the other DPS classes have team synergy abilities as well, though less blatant (e.g. one of their attacks might apply a debuff for a particular damage type that other team members use as well).
