I have to move an existing exterior light from the underside of my deck to an exterior wall where the deck ledger is mounted. The wall is a stucco covered block wall. I am wondering what type of box I should use as well as how to route the existing wire and cut the hole in the block for the box. I want to have the box recessed so that the light fixture is flush with the wall. I am not sure if the block core is hollow or filled with concrete. Either way, I will have to route the feed wire from the inside power/switch to the fixture. Thanks for any info..

You are asking to much to have this box flush mounted. IMO. Unless you are very good at stucco and block work.
Cables or conduit in your house? I would install a box or condulet where the old fixture was and run 1/2" EMT to where the new location is. Mount the new box "surface mount" and fixture and be done with it.

The box pictured is for outdoor use (wet) and will accept flood and many other fixtures and devices. We call them "Bell" boxes in the trade.

You can use this box where the old fixture was also. Put a cover and gasket on it.

I already have some of those surface mounted boxes mounted on my deck for receptacles. I need to have the box flush mounted (somehow). I already have a receptacle flush mounted on that wall but the location is closer to the door and I would like to have the light mounted somewhere in the middle. I originally ran underground wire to the fixture on the deck and was hoping to use the same length of wire. The interior wall has paneling on a block wall. The paneling/drywall is over furring strips.
