@geerlingguy: Consider checking out some global latency comparisons between StarLink and cable. I believe their long-term plan is to have the satellites route traffic between themselves using space lasers rather than hit a ground station and traverse undersea cables and the like.
Not sure if they have that fully implemented yet, but might be interesting looking at the path and latency traffic to .au or Asia or Africa takes on Starlink vs cable. A couple factors may come into play: "as the crow flies" and light speed in vacuum vs glass.
I know Evi Nemeth (RIP) talking on the CAIDA project showed some nice graphs of the "speed of light cone" re: latencies vs. geography. See about halfway down on this: https://web.archive.org/web/20160103034640/http://www.isoc.o...
