I think with bench a lot of the time it comes down to people's body mechanics and what they can handle, of course for Powerlifters many do bench wide for comp reasons, allowing them to move the most load.
But I know people who simply cannot bench with a closer grip, and vice versa, just feels horrible for them.
I find its the same with all the compound lifts, your body, the natural leverage you create, and your mechanics often dictate how much you can move.
Fwiw I dont like a too wide grip on bench.
