Good point. However, the 600 is almost twice the weight of the RF 100-400,

Are you sure about that? I thought that the RF100-400 + RF1.4x is about 1.9 pounds, while the RF600/11 is about 1.7 pounds. The RF800/11 is about double the weight of the bare RF100-400.

and I guess twice the size since it needs to be extended to be used. And no zoom.

I hadn't realized how much those extenders weight. I stand corrected.

So the 100-400 zoom trades off some IQ for a slimmer but heavier package than the 600 f11, extended length seems to be about the same for both; but the zoom gives variable focal length, and maybe better AF (nano-USM v. STM)?

As always a tradeoff between IQ and size/weight/convenience. Both are nice options.
