If beating works best on your C-scow, then good. I find on lightweight sloops (like a Scot) you heel more, the shifts can be volatile and you could possibly get caught aback or quickly in irons if you were close-hauled before the shift
I prefer reaching (maybe close reaching) over beating or running in a squall (assuming I have a choice given the geography). It's easier to luff without losing steerageway, and easier to re-accelerate if you had to let the sails way out.
You can maneuver either up or down if you have to avoid someone/something, and in no-visibility conditions, navigation is easier if you're not tacking.
Running risks a jibe if there's an unexpected windshift, and you may be overpowered, bow digs in, you can't luff. Also, I agree that running could keep you in the squall longer.
But others' mileage may vary, obviously.
