Heavy and light crossbows have two-handed ownership, so you must get the sting with your free object interaction. After use, you can not reload the crossbow.
The arches are much better
If you do do not Have the crossbow gift, even a short bow deals more damage in two rounds than a crossbow or a crossbow + a dart.
If you make have Crossbow Expert, a hand-held crossbow provides the best DPR.
There is no situation in which a handless crossbow is a good option for the DPR if you have Extra Attack. I would say even if you do not have EA, hand crossbows are the only good crossbows.
