What about using archery and then choose dual wielding?
They don’t synergise well for your traditional ranger. If you’re mainly going to be using a bow, the dual wielding feat isn’t going to help with that at all.
And if you’re going to mainly be using two weapons, then dual wielding doesn’t replace the benefits of two weapon fighting. It gives a bonus to AC when holding two weapons and lets you dual wield non-light weapons, but doesn’t allow you to apply your stat bonus to damage with your second weapon unlike two weapon fighting, so you’re not going to be able to do full damage with your off hand.
I’d say that, if you’re a dexterity based ranger, the dual wielding feat in BG3 isn’t particularly helpful, as most finesse weapons are light and so can be dual wielded anyway. So, unlike for a strength based warrior, the only real benefits of the dual wielding feat are the +1 to AC and the ability to dual wield rapiers, and in my view just boosting dexterity by 2 is likely to be competitive with that. Plus the latter helps with your bows as well!
