Doesn't change your overall point, but just to comment on the Fiesta case (of interest to me since I drove one of the first model year's return to North America - 2011 - until earlier this year) - it only survived 4 extra years outside of NA - it's discontinued worldwide as of 2023.

The surviving vehicle(s) on the platform are the Ford Puma and Puma Gen-E, which are subcompact crossovers not sold in North America.
