For a start 'empowerment' is a really stupid word. It sounds like the sort of thing an overpaid manager with no idea as to what they are doing would use.
I'd lose it for a start its probably stifling your creativity and making you think in the wrong direction.
But French Noir is definitly the right direction. Not so much 30s, but there are loads of great Traffaut films with great plays on shadow and light that would help you.

I depends how the word is used.
Empowerment of employees is often misinterpreted as a method of transferring blame.
Empowerment as a social term, e.g. empowerment of women, of minorities, etc is very descriptive.
It would be short-sighted to disregard the term as stifling without exploring the possible interpretations of of the term in relation to the project. It may be an AS-level assignment, but there is an opportunity to demonstrate a very high level with a topic like this. Disregarding difficult terminology from the outset will almost certainly result in self-exclusion from the top marks available.
TBH, I think you've done well to avoid the "sensual" angle, as glamour/porn have very little to do with empowerment of anyone but the photographer and the viewer.
Film noir very succesfully identifies with shadows, but how does this relate to the concept of empowerment? What is it about the shadows that gives power to one character or another? Is it just characters that are empowered or did this style of film-making also transfer power/importance to the location?
Film noir is also a very literal interpretation of shadow. What else can shadow mean? It could also be interpreted as out of the light (out of the limelight?) and out of sight, or in the margins.
If the shadows are the margins of society, then is social photography the act of empowerment by making marginalised people/societies visible? Historically this could include the depression era photography of Dorothea Lange, in contemporary times this could include coverage of homeless, migrant or other disinfranchised members of society.
Just throwing out some other ideas for you.
