Never been to Bukidnon. I can say if heat, polution and health concerns are an issue I would avoid Manila, Cebu and Davao but I would also try to be close if getting to quality health care is of concern. Of all the places I have been (and there have been more than twenty) Dumagette might be a consideration. As well as San Carlos. And Iloilo.
Each have some city amenities. Development, giving you housing choices. An existing expat community. And good vquality of life - at least to me.
Again, my advice is try it for a while before deciding.
Good luck
