There are basically two ways to approach this. In both cases what you are doing is increasing the amount of total light that enters the camera so that the random nature of photon shot noise is minimized by the increased amount of total data (photons striking pixel wells). Long exposure images shot at lower ISO when combined with dark frame subtraction. ...
I'd say highly detailed because a) noise in low detail areas stands out, and b) where there's detail, noise can actually make an image appear sharper. This only applies if the size of the detail is larger enough compared to the size of the noise pattern.
If you're shooting in low light, the noise is mostly caused by the randomness of the number of photons hitting each sensor sight. So in one sense what you're shooting doesn't matter. But... you can reduce the noise a good deal if you take multiple exposures of the same scene and then stack and average them in post-processing. So my answer is a static subject ...
