SE would do well to take a page out of Genshin's book as far as surveys go and I think it'd be super interesting if they went through with it properly vs the fairly wet efforts we've seen of late.
You can answer them right in game (And get small rewards to encourage you to do so), if you answer negatively it'll actively ask for further feedback and whilst they are still primarily multiple choice, they tend to be flexible enough for you to stick the knife in if you're so inclined.
In a game with such a multilingual player base as FFXIV, these sort of surveys are the way to go if you really want to gauge the player base as a whole IMO. Granted I'm not particularly convinced that SE are in a position to actually do much with the info whatever it may turn up,
but that's a different topic altogether.
