According to SeatGuru . you really would want to avoid row 4 then as there is no windows there!
That leaves 3 and 5 back and as you say looking at the engine happens a lot.
3 would be the 'best' forward view tho the props are probably directly even or slightly back.
the last row 14 has no recline so 12 (no row 13) might be the only other option looking kinda under the wing.
