I'm with Sal on the lacrosse gloves, though I'm going to diverge on the padded fencing gloves. If they're like mine, or the ones I've seen, they won't prevent a broken finger if you get whacked really good. The problem I have with lacrosse gloves is that there is no padding on the edge of the first finger and the top and bottom of the thumb, and it's very easy to get hit there, either because the hands were the target or because you interceded them trying to block the body and screwed up (I've done this a ton of times, by the way, trying to get a hängen in there a bit too late).
I actually modified my lacrosse gloves. I'd go a picture but my wife has the camera today. It's a pretty simple fix, though. I use those interlocking mats you can get to put workout equipment on or for kids to play on--it's a really stiff foam, but it's easy to cut and work with. I cut a pad the size of the area I'm going to cover, say from my hand to the first knuckle. Then I cut a piece of an Ikea trashcan I got for a buck on sale--it's a round wastebasket made of polypropylene like this one:

Anyway, once I have a plate to match the size of the foam piece I have, tyhe natural curve of the trashcan dishes nicely into a convex piece like you'd probably make if you were armoring for yourself out of metal. I just taped the two together, with the hard plate on top, and then taped tho whole thing into whatever part of the lacrosse glove I was trying to shore up, and it really seemed to reduce my painful finger hits and low-grade injuries (severe bruises, swollen fingers, etc.) quite a bit.
Of course, all of this depends upon the type of lacrosse gloves you have. Mine are Shock Doctor, which have a bit too much space between the fingers for my liking when you close your hand, but I haven't really tried to fix that problem yet.
BTW, I'd have to agree with you regarding control. It's a great safety measure, but mistakes still happen, and it's really impossible to set the bar that high if you have a group of mixed experience levels like most of us do. Someone will always do something like land a shot that was meant to hit further along its arc but the hands got there first, so the focus point of the blow was later and they take the full force of the torqued arc on their hands. That's why we require sparring gloves here, even for padded work (which we still do, but that's another discussion for another time), but particulary for plastic/wood sparring.
Good luck in the search.
