Do you want french azerty (ISO), or international qwerty (ANSI)?
Also do you have a switch preference? If you never tried any mechanical switches, I suggest you look for a store that has some on display that you can try out.
Here in Belgium there's a bunch of stores, like Mediamarkt, Alternate and Tones that allow you to try out display keyboards, and I'd highly suggest you find one as well.
I bought my first mechanical keyboard without trying any, and later on I realized there were other switches I liked much better.
