I definitely recommend it. Alts are a great way to experience a race you've wanted to try without having to use a fantasia, as well as a change to explore new jobs you haven't done before. I see you joined the forums in 2017 so assume you were around before the changes to ARR and HW. Going through those again is worth making an alt all on their own. You'll be amazed at the details you've forgotten or completely missed thinking they weren't really important.
