Is numbeo accurate?

We are in planning stages for moving over to France permanently. Likely the occitanie region. I am trying to be as accurate with our budget as possible for we will be retired. (More like the Mr. Money Mustache version of retirement not a large disposable income type). I'm curious if anyone can confirm the numbeo data for groceries in particular. We live near Albany ny. Also, maybe some unexpected reoccurring expenses that were unforeseen.
