It seems to be about 50/50 which one a given game has it defaulted to.

Bonus question: hold or toggle?

spoiler

Ctrl + hold is obviously the superior choice

      If there's some kind of crouch slide move I often end up double binding crouch to a mouse button.

      i’m pretty used to toggle crouch myself because that’s how consoles games work for the most part.

      I think Halo had holding for crouch right from the start- things like crouch jumping and t-bagging would've been kind of clunky with toggle (though it was always an option)
