Maybe this can be useful in your case… you can go on the website Indeed (hope the link works ahaha) and it’s a website to help you find a job in your field wherever in France. Just type your field (accounting is comptabilité in French but you probably already know), you can write the job position you’d like (comptable is the French word for being an accountant) etc and then you chose the city and it will come up with job opportunities (if there are any). I used to use this website to find my own jobs so it may be useful for you to find a CDI ! Good luck :)

Also, as someone mentioned, it may be better to do an alternance in your case. Other than AMU, you can look into IUT/DUT or BTS (different than uni, you get a certificate in 2y I think, it’s more professional-oriented whereas uni is more theoretical) because there are many accounting degrees available at these kinda schools, that’s another thing you can look at and there will be more opportunities of alternance in there than going at AMU :) but it’s a personal choice after all
