My Fenix 5S sapphire is showing cracks on HR sensors although used with case and has almost zero scratch anywhere else on the watch.

The superficial cracking that you are seeing should not impact the OHR sensor itself since the cracking is the protective coat on top of the OHR sensor glass. As long as the glass is not damaged on the OHR sensor itself, your watch will maintain its water rating and continue to work the same.
So what I am getting is this cracking on protective layer is supposed to be happen no matter how well you are maintaining your watch!!!!
