Polytechnique and a few Écoles have English language direct programs meant for English speakers (whether French, European, or international), distinct from the poorly-funded bureaucratic nightmares that are regular university programs. Even the French-language special programs such as CMIs and IUTs (see below) would be more supportive than licence, especially licence non selective.
Your best bet is to apply to the Écoles via CampusFrance - the process begins in October through December, with a Dec 15 deadline where you list 3 programs at a University or 3 universities.
For Écoles each will list the process on their Parcoursup page and there should be a contact for the dean or professor in charge of the program. (For special programs you go through Parcoursup not Campus France).

→ click “modifier les filtres” and then check the box in front of Formations des écoles d’ingénieurs. See what pops up with “international” or English language info. Click than as “favori” to keep them in your folder.
All STEM programs will expect students to have taken Calc BC and AP stats. If “spé PC” is listed it means one AP Physics + AP Chem.
You should start with these three:
===.
UTC, UTT, are a Grandes Écoles/Université mix.
===
IUTs are smaller colleges, with hands on/ experiential learning and co-ops.
===
CMI are STEM honors colleges at public universities. Examples
Doubles licences and licences sélectives tend to offer more support than regular programs but still.. not recommended.
Anything at a Université would require an excellent ability to navigate bureaucracy and confusing rules, a high threshold for frustration, etc.
