Thank you very much to everyone for the answers, you are very kind.
Surely the main thing will be playing the role, I will not make choices to have perfect statistics.
However, I think it is rather difficult to have a credibly strong character in both weapons, correct?
It's very easy. Dexterity is the primary stat for both finesse melee and ranged weapons. Picking two-weapon fighting style at level 2 will let you be effective with both dual wielding and archery. And since you're a Ranger, picking Hunter with Colossus Slayer at level 3 will make sure your damage with both is good for all of the early access.
You can go Beast Master or pick something else from Hunter than Colossus Slayer, but that is harder to play effectively, so I recommend Hunter + Colossus Slayer since you're new to the game.
