Or stuff like "cow" (from Old English) vs "beef" (from Old French). Which kinda makes sense when you consider who grew meet vs who ate it.

It's a pretty common thing worldwide, though. French played a similar role as upper class marker in many other countries that were influenced by it when France was at the peak of its global dominance. For Slavic languages, German also played this role at one point, and IIRC there is something similar historically with Chinese in areas in its cultural dominance.
