I can’t speak to the Xbox stuff but for the most part I feel the Dawntrail launch has gone really well. Yes, there’s some bugs, that’s usually inevitable for a launch of this size, but the only game breaking one I’ve seen was Syrcus Tower which was fixed in under 24 hours without bringing the game down for maintenance.
But I don’t think there’s been anywhere near as many queuing issues as there was in Endwalker, and while I’m only just past the first dungeon in the MSQ the only issues I’ve seen (other than ST) have been cosmetic.
Someone crunched the numbers and worked out this was cheaper than dealing with people wanting refunds of their DLC content when the main game was delisted.
