The lander size under consideration is about 40x that of the Martian rover, I don’t know that a sky crane would work as well without a parachuting stage and atmosphere, and finally it seems rather unhelpful for taking off.

I presume this is part of why SpaceX is planning to use landing thrusters that are higher up the rocket.

Afaik that's mainly so the plume of razor sharp dust doesn't tear their engines to billion tiny pieces. Unlike the LEM, they won't be bringing a spare for liftoff.

Doubt 100meters will be enough.They need to be much higher not to kick regolith toward the rocket and beyond.
