Not a polarising filter - that reduces light everywhere. Beyond that, it depends on the effect that you want.
If intended for a competition, I have been told that silhouettes are marked down as technically inept even if artistically justified, so people tend to try to get detail. That means reducing the light in the sky part and leaving the foreground unaffected, which is the job of a graduated neutral density filter. Soft grad is probably better for you.
Alternatively, tripod mount and make more than one exposure at different settings to get the sky and foreground as you like it and merge in Photoshop. Or use HDR software.
Settings as always depend on what you want, and the conditions at the time and place. I couldn't possibly advise on that, although given that digital exposures are cheap, you could experiment to find out how far off what you want the camera's meter is.
