If you plan to continue your academic and didactic work then you should first consider the choice of a scientific institution in which you will be able to develop your scientific interests and continue your research in the chosen topic.
All of those things - if you wish to continue a career within the academic setting - or even research within industry. The only thing that you haven't mentioned is the possibility of pursuing a specific post-doc research position - within or outside your current institution.
Thanks all, I know that it's not easy to make research within money from industry, (as CIFRE help) but in fact in social science and in my specific field, we don't need too much financial ressources...so, it's okay to keep your subject and pursuit your research. But it's more complicated to find a titular job as a teacher in University right now in France, for most academic fields (applied sciences or human sciences).
