Installing patio door with nail flange in concrete block

Hi. I am installing patio sliding door in a concrete block house. I received door with a nailing flange/fin instead of one without the nail fin which I ordered. I was waiting for the door a few months and I already have the opening ready so I will install these. I am not sure what would be the best option of installing it.

Should I build a treated wood frame in the middle of the concrete and attach the door flange to it OR would it be better to attach it to the exterior wall?

The first option would match my windows and other door which are installed in the middle of the concrete blocks depth but it would be more difficult to do and would require a bit larger rough opening.

Second option is much easier, I wouldn't need to cut the wall and finish the exterior with stucco. But it would stick a bit out outside and would require a mounding around it and I would need to think of a way to finish the interior floor gap etc.

Which option is correct and better?
