yeah, if you can spare 500 jewels, I'd go for the +50 DC, then try to max all 3 of your barracks ASAP. If you don't want to spare the jewels right now, then maxing barracks should take at least 1 of your workshops going forward.

DC was really the first thing I spent jewels on in the game, and I'd highly recommend it. Being able to get a full HSR team will strengthen you a lot.
