I think the big difference is that the characters in WotR have a defined sexuality independent of the player while in BG3, depending on your viewpoint, everything is bi or playersexual (meaning their sexuality changes to always be compatible to the player).
Di they? I never really bothered chasing romance with anyone so far, but as far as I could remember even in Kingmaker you could basically flirt with the entire cast.
Party control in Baldur's Gate 3 is a complete mess that begs to be addressed. SAY NO TO THE TOILET CHAIN
