This is exactly opposite of my experience with BG3. I played it twice (good sorcerer and evil Dark Urge) and made completely different choices and I felt like playing different games. You may have a different view on this, sure, but it doesn't mean it's a reality.
There are things I don't like in how the story goes or things that feels unfinished or cut, but the feeling of meaningful choice is on of stronger points of BG3.
I don't want to say simple "please, play the game first", because I formed opinion on games I haven't played myself too, and there is nothing wrong with that, but it's... really not how you described with BG3, at least to me. In fact, playing BG3 made me put more attention of lack of meaningful choices in each crpg I played after BG3.
Like, Rogue Trader is a game with truly stellar writing (really, something I haven't seen since Disco Elysium), but the choices mainly comes down to following one of three paths (dogmatic, heretical or iconoplast). There is no sense of "role playing" your character the way you can do in BG3.
