Workflow: (Your guarantee for professionalism)
Shot RAW, develop in capture one pro, import to Photoshop in a 16 bit TIFF file, manually clean image for dust, small particles and trademarks, save to TIFF, re-edit after a few days and save to jpg for upload.
I never use any noise reduction, except for dark areas without details.
