Can anyone suggest a utility that takes an audio file as input, and can output to a text/CSV file various data (RMS, peaks, dominant frequencies, etc.) per each N ms of the input, for both time and frequency domains?

Windows is my main target, but *nix as well.

It seems SoX has a few features in this direction, but not flexible enough (e.g., data per N ms, frequency domain resolution).

If you don't want to write an application yourself, Your best bet is probably MATLAB or a MATLAB Clone.

Of course, you'd need to understand the math required for what you want to accomplish. I've never used any of these programs, but I believe FFT is "built-in" (and simpler things like average & RMS algirithms) so you shouldn't have to develop all of the math from scratch.
