Definitely a road frame.......Your one consideration to beware of is that if it is indeed French you might be dealing with French threads on the fork and bottom bracket. If you need to replace either of those it may be relatively expensive and or frustrating to find the parts you need. Also if it has 27" tires and you switch to 700c's your brakes (if you wanna run them...which I would) might not reach far enough to hit your new rims. Also the stem & bars are likely different sizes than those commonly used on the majority of older road bikes so if you want to swap them out too you might run into problems. French bikes can be funny like that. But it really no biggie.....
