One thing I do is set the camera to give me somewhat (but not completely like raw) flat images OOC. Post usually includes bumping up contrast, color and adjusting exposure slightly and maybe tweaking WB, and cropping/rotating. Except for cropping/rotating, the other adjustments are often the same for all shots in a series so I work it out once then apply to all.
Shooting a bit flat gives the JPEGs more wiggle room than going for super saturated and punchy right OOC. I read Ken Rockwell has a Vivid JPEG preset he uses but I don't. If I forget to switch the preset back when I go into a low light/high ISO situation, I get crushed files. So I just use one JPEG preset for everything and punch in post as needed.
If you are PP your images, wouldn't it be better to just work off of a RAW file vs JPG since there is no realized time savings. If using LR, import file --> correct one image --> sync them to the rest of images --> export. Whether RAW or JPG, time spent is the same.
Now if you are just delivering SOOC images than JPG would be the way to go.
The one variance is file size but in this day storage is pretty cheap.
