The day tank holds 24 hours of fuel at normal cruise. All fuel entering the
day tank goes through a pair of 1000FG filters with 10 micron filters and
water sensors in the bowls so all the fuel is filtered rather than a
recirculating polishing system that filters the same fuel over and over.

I would argue for using 2 micron filters. Get the crud out at the
earliest possible point in the system. 1000FGs should last almost
forever feeding a sailboat engine. I have them out in front of a pair
of Detroit 671s and they are typically good for 500 to 1000 gallons
between element changes (2 micron filters).
