The exits at Doors 1 and 2 are from galleys, so no Polaris seats are considered exit rows from a legal standpoint. Odd D/G pairs are the only seats where can really see another pax; anything else and your kids are going to be somewhat on their own (probably just fine at their age). Galley noise is comparable to other aircraft - it bothers some and not others. Personally I don't think the footwell makes the bulkhead really "worth it" but almost any odd-row Polaris seat is a good pick.
