First, I consider you've got a really enough good background for bschools in France. You should have compensatively taken TOEFL or IELTS if you wanna apply either MBA or MIF.
For MIF, I don't think it's appropriate to study Finance for only one year without any professional or academic experience in that area. And the admin offic will also consider it, I think.
Most of the MBA and MIF courses are taught in English, hence Toefl and Ielts may be required. I think you can try MIF in case of your limited budget or apply for some scholarship while going for MBA
