Only the light crossbow and shortbow are availible atm I think? Druids don't have proficiency, which means you won't get any bonuses (it's a simple 1d20 to hit). It's not idea, but it's not useless. You can equip both weapons, if you check your character via N (be default) you can see you have 2 slots. Bottom left of the skillbar ingame has a swap button too.
I tried to equip a light crossbow but the game doesn't allow it because the lack of profiency. Not so much of a problem, at the moment, because I'm making plenty of the animal forms in combat and almost all my party have long range spells or cantrips (I made Astarion an eldricht caster).
Ouff, @handzum, I get your point but when I create my toons I'm the kind of player that goes by tne inspiration of the moment (that is: now I'm playing a very narcisistic half high elf with guild artisan backgrouns that I choose because it gives profiency in insight and persuasion something coherent with narcisistic personalities that usually are skilled manipulators). *^_^*
