No difference. You're just "filling the tank" so to speak, how fast you do it doesn't affect the "quantity" required.
There are some footnotes. Level 1 charging (120 volts) is about 10% less efficient than Level 2. And I've seen some folks make the case that Level 2 charging at a higher amperage could be slightly more efficient than at a lower amperage because the car's systems/cooling run for shorter amount of time, consuming less power, though this would be minimal.
Edit: One additional thought, not sure yet how this applies to the ID.4 as I'm unclear about battery preconditioning for set departure time. With my i3, which preconditions the battery for a set departure time, charging at a higher amperage in the 3 hours just before departure time warms the battery up as a byproduct of charging, whereas charging at a low rate relies entirely on the car's 1kW battery heater to kick on and do the job, and that heater can consume 3kWh of electricity over the course of 3 hours on a cold morning. The ID.4's battery heater consumes much more electricity (it draws around 5kW; not sure how long it needs to run). So potentially a higher rate charger will have a similar effect of not requiring additional heat to be created and externally induced, if the ID.4 actually preconditions based on a schedule.
