Capture Sharpening - simply thank you 😊

This is a followup from my earlier question that I’ve posted on the dt 5.4 announcement:

First time for me trying the new capture sharpen option in demosaic, I’ve read the github discussion mentioned in this thread but I wonder about the “contrast sensitivity” value.

Consider this first exampe (iso 100, good lens/good camera/good light – eos r with 35mm f1/.8):

I have increased the contrast sens from the default which was this, (the thinking was, I’m applying this to the flat parts of this image so I should dial it back i.e. increase it from 0.27):

Is this sort of reasoning correct?

Now an example of an ISO6400 image (same camera, eos r with rf70-200 f4): do I accept the increase sharpening of the noise?

…or should I again, “dial it back” i.e. increase the sensitivity to 0.48 and only focus on the subject in foreground?
