I can see that most of the newer jobs start or unfold in Ul'dah. Even BLU, which starts in LL takes you to Ul'dah right away. In comparison, LL gets a couple of jobs, and Gridania gets only one. Is there a lore reason why Ul'dah is so important or is it mere practicality (e.g. most players choosing Ul'dah as home city)? This really makes Ul'dah feel like the "canon" starting city from a lore-perspective.
