I'm not sure to which point it would be so great to add steam, since it's already expanding and would displace some oxygen at the intake tract and decrease the effective compression. Water droplets might be still better in the end, because there is more expansion left to happen inside the cylinders and it may retain more residual heat that would otherwise be wasted through the cylinder walls.

Well, unless doing direct steam injection, jou cannot really add steam. I fairly wuickly heats up the air and becomes droplets.
Have a look at your kettle boiling. The steam is transparent. If you can see it, it is liquid droplets suspended in the air.
