Everything you want is subjective, but i would second ninja for you, seems like a very fast class from what I've done with it. Seen some really nice armor combinations too. the ninja flip flops all over hell and looks damn good at it.

I really enjoy bard but it's not complicated in the slightest. Bards have very flamboyant aesthetics, some of which i find look amazing.

the other classes i've really focused on and not just leveled were healers so there is my two cents.

Also its pretty cool what people have done with glamours in this game. just head over to eorzea collection website and check em out, you can also apply filters to it. might help.
