I love wisteria blooms, but I'm not a fan of the plant. It can be invasive. I know what I'd do with it.
I would have done the same thing to the rose. It will probably be happy to be pruned. I'd hack it way back next winter-spring just to keep it rambling in a desirable direction.
Butterfly bush is the common name for a few different plants, but I don't think either would suffer from a serious haircut. We grow Buddlia and it freezes back each winter. I just shape it a bit and let it go nuts. If it gets unruly I just break out the loppers. It will probably put another flush of blooms out if you don't mow it to the ground.
In general, I'd just neaten it all up and enjoy them for the season. Once winter rolls around it should be less work.
