My favorite scout plane was KI-67 bombers. They are very fast, climb great, and have extremely long range on a full tank. Ive been up in them for over an hour a time, far behind enemy lines hitting ords...ect Ive ran into all kinds of things, CVs, missions...ect. At 15k , and about 330 mph, you cover a lot of ground. If we ever get the A-26, or even the TU-2, they will be the perfect CV scout bombers with the speed of a KI-67 and the hitting power of B-26s.
I would guess A-20s would do well too.
