My first stop is to enable the profiled-denoise; I find this does quite a good job if I have not had to 'pull' the data heavily. As a second step, if needed, I then use a very small value of raw-denoise.
I am finding that I only need to use the local-means and bilateral-filter if my initial exposure was badly misplaced or I have been heavy handed with correction. I recently moved from a Canon (older model) to a Fuji and the change in noise reduction is remarkable. I suspect that for every camera there is a different approach to the problem.
