When considering what fictional society I would "like" to live in, I always try to imagine myself being on the lowest sociopolitical rung of that society's ladder, since it actually would be nice to be wealthy in Ul'dah or a Governor in some Garlean colony.

So that immediately rules out Ul'dah and Thavanair and any other city with a apparent poverty problem, Garlemald is also out since I wouldn't want to be a ceruleam mining slave.

Eulmore under Varuthy as a servant for the free citizens would be alright if I had a marketable skill, but living with the fear that if I ever messed up or annoyed someone I could be arbitrarily thrown off the balcony would be too anxiety inducing.

Everyone seems pretty equal in the Crystarium, but ekeing out an existance on the first would be emotionally fufilling but demanding work.

Sharlayan doesn't seem to have much of a poverty problem, so I guess I would be a gleaner. It'd be a lot of physical labor, but it seems like I would be well compensated and my rights are well advocated for, also I would get to travel a lot.

In the Ancient society, I suppose I'd be a familiar. Which kind of turns how good existance is into a dice roll, maybe I'd be a familiar for someone who values me as an equal and research partner, which would be the best possible outcome. Or maybe I'd be a familiar for one of those ancients who thinks it would be fine if a creature in Elpis killed me, which would suck.

A lot of these choicea have pros and cons, I'd probably lean to either Sharlayan or the Crystarium, though.
