Don't think of it as strength vs constrictor cause if things go awry it doesn't much matter how strong you are, when dealing with large constrictors, the snake is likely stronger. Larger and stronger people will have an easier time manipulating a big snake but anybody who thinks this advantage goes beyond that is delusional. It's highly unlikely you will be viewed as a possible food item because of your size. These accidents are almost always a failure of the keeper in following good husbandry or handling practices. There are some dwarf localities you may want to look into as well - all that retic personality in a smaller package.
