Except for weapons designed to penetrate plate armour, axes, hammers, pikes, spears, daggers...
Actually i recall seeing various tests against plate armour (directly to the chest, possible the best case scenario) and one of the things it defended against best was crossbow bolts, they tended to be made out of rather mild steel or even iron which made them terrible at penetrating plate armour more than a cm or 2 at best, with adequate linen padding it would generally be a minor wound (not counting infections).
However, against weaker parts of the armour, joints, eye holes, gauntlets, hits close to bones, any areas which would be lightly padded, the effects would be far more wide ranging anywhere from incapacitating wounds (even a broken finger could end up being fatal in thr front line), broken bones, torn ligaments, torn arterys, and of course a bolt to the eye was pretty much always fatal.
I'll have to admit crossbows in df are overpowered against armour, but it's nothing that a good material rebalance shouldn't fix, as long as we still get good impacts against other body parts i expect things should start being more realistic but still damn fatal (as long as those damn legendary shield users stop swatting bolts from the air like flies).
Feel free to disagree with me, i'm just offering my opinion
