Most of my woodworking has involved using power tools as much as possible and I've found wide chisels very useful for the things power tools can't do. When mortising for butt hinges, which I have usually done for up to a dozen pairs at a time when doing casework, squaring out corners is what a router can't do. I have a 2" E. A. Berg chisel that is about the length of a butt chisel after maybe a century of use and its width makes it easy to register against the back or side of the mortise when removing the little bit of wood in the corner. I hold the blade in one hand and place the back against the existing ledge from the router and then push on the handle with the other hand to shear off the wood. This could be done with a much narrower chisel but the long registration provided by the wider blade makes the operation quicker and more controlled.

My very favorite chisel would make traditional woodworkers roll their eyes and dismiss me as both a woodbutcher and a fool. It's a 2-1/4" Japanese chisel that I converted for use trimming parchment on inside corners. The conversion involved bending the shank enough that the handle was out of the way so I could use it for flush trimming. The amount of time it saved me on its first job more than paid for the cost of the chisel and it has come in handy many times since then even though I no longer work with parchment.

Both of these examples work better with a short, light chisel. I own a much longer 2" chisel but never use it.
