Realize that JPG is almost always good enough.
Actually, the pictures modes are very practical to adjust your preview to your preferred post-processing style. When I know I'm going to do a B&W series, I set the picture mode to B&W with high contrast. I still shoot in RAW and I will do the B&W conversion in Lightroom, but the embedded JPG will be B&W, and when I review my images on the camera, I will have a much better idea of the potential of some of the images.
