I am becoming more and more convinced that one of the easiest autorotations to do is the 'constant attitude, no flare' autorotation.
This presupposes that you really don't care where it is you land - all you want to do is walk away from the crash, so we'll leave out the "have to get to a particular spot" aspect for this discussion.
The airspeed for this type of autorotation will depend on the helicopter - probably a slower speed than will be used here would be appropriate for a Bell 47 and a higher speed than used here for a Bell 407. For the Bell 206 series, I use 40 Knots plus half the windspeed.
After turning into the wind and setting the airspeed / attitude there is nothing to do until the ground starts to rush up, which is a pretty strong cue from below about 75' AGL in wide open territory. At this point, application of collective has to wait until about 20-25' above ground when it is applied smoothly and positively.
The helicopter is in a slightly nose-up attitude so applying collective will both slow / stop the rate of descent and slow the forward speed to something that would be survivable.
A couple of demonstrations and even very low time fixed wing pilots can fly it.
But the point is, you don't need to have airspeed to survive the landing - just a way to get the rate of descent and forward speed to something survivable.
I think there is a strong case to be made to teach this technique first and when the pilot has slightly more experience to teach the use airspeed and rotor RPM to get you to a desired spot and learn how to flare, etc.
