I used to think I might get away with something like a Dark Urge Warlock but no, the game very strongly pushes the Dark Urge to be a Rogue Assassin as his patron. We know the first item you get from the dark urge origin story and it's an insanely powerful cloak that is 1,000,000% intended to be worn by a rogue. Other classes could technically make use of it but far less efficiently. So I think it would be far less ideal to be anything but a Rogue Assassin when playing the dark urge. You could play the Dark Urge as another class but then you'd have to hand the insanely powerful Rogue gear obtained by the Dark Urge to Astarion or maybe a rogue hireling or not use them...all terrible ideas.
I wouldn't think of any choice here as canon though. Whatever you choose and whatever you do is equally valid in terms of the game's story...you know, as long as it's a good enough build to progress through the entire game and you don't get murdered every fight. This is likely to be the end of the story of Baldur's Gate and the dead three...this is it. There probably won't be a BG4 and if there is it'll have a totally unrelated story and all events of BG1-3 will be entirely ignored. So I don't expect either Larian or WotC will ever declare any "canon" for BG3 like oh only this one of the 37 endings or whatever is canon and if you played the dark urge as another race than white dragonborn you were wrong, etc.
