Shocks may feel stiff but internally be blown at high rebound/compression. Try swapping sides if it's easy.

Thanks for your thoughts robnitro.
The shocks could probably be swapped temporarily. But they have tabs to hold the brake lines that make them only fit correctly on one side. If I knew the clunk wasn’t a serious problem, I’d start replacing stuff, starting with the shocks, till the clunks went away. But I’m running out of time before we really need the X5 working well.
I reinstalled the right shock and removed the rear sway bar completely. The clunks did not change on the test drive
I got in the back with the seats down while my wife drove over the test bumps at 20 mph. The clunks are very distinct and occur in rapid succession: clunk or clunk-clunk, or clunk-clunk-clunk depending on the size of the bump (roughly 1-2in asphalt road patches). It really sounds like something is loose under the rear seats and bumps into the frame when we drive over the small bumps. I may take out the rear seat again to see if, by removing the styrofoam fuel pump covers, I can hear/localize the sound better.
FWIW I didn’t try getting to the fuel tube because of the number of “break & replace” plastic fasteners.
