FWIW, I don’t think Jefferson was a naturalized citizen of France. To me, someone naturalizes because they want to live in that country as a citizen, and will remain there unless they later change their mind. I don’t think Jefferson ever had the intent to spend his life in France. The same would apply to other leading American citizens of the time.
I haven’t researched it, but that is how I view it.
Thank you for your response. It appears to me to be a perfectly reasonable analysis of the available information.
