I don't see how the tabletop Ranger works in a CRPG. All of their abilities are about removing any disadvantages in set situations - and if you don't pick the campaign's situations you've got a useless character. There's already been articles on how the Ranger for BG3 needed to be redesigned to function in a CRPG at all:

I know that right now already they have the summoning for animal companions implemented on what I assume is the bones of the Summoner spells from DOS2 outside of combat (For PCs at least, enemy Rangers can just drop their companions on the middle of your party right now.) They have always been the most RP heavy of the classes because of the favored enemy and natural explorer features. --Because you're right, they're useless if the game doesn't revolve around how impactful those two choices are. A Fighter with a bow joke can be inserted here.
Honestly my quickest fix for something like this at least for BGIII is to give them a more generalized set of class feats for early level that have to deal with navigating difficult terrain, minimum bow and missile range, (threatened debuff is weird in general) and more utility out of having the pet around so it isn't just a souped up Find Familiar.
