Noise reduction with 35mm scanned negative film

My impression, confirmed by some of the research I’ve done, is that scanned negatives tend to be more noisy on screen that they would be when printed in a dark room.

I mostly scan films because I don’t know yet how to print in a dark room. What would be a reasonable noise reduction setting in Lightroom to make the photo on screen look similar to what it would be when printed in a darkroom?
