"Having that said," is a good option to replace "for this reason" with. You could also say something like "Given the aforementioned information." There are plenty of options at your disposal. Your choices are OK, but it's better not to repeat the word "this," since you're stating it later on in the sentence. You could say "Incidentally," as well.
