Hi Justin,
WP caching plugins in complex themes usually cause more trouble than they fix (and they’re not even really needed, unless you have thousands of unique visitors per day).
Such plugins not only can break the Javascript in a theme, but are also dependent on your server’s setup – so that’s why we can’t really make such recommendations.
Cloudflare should be more than enough (I personally run only Cloudlflare on a wallpapers site that gets ~70000 unique visitors monthly). Hope this helps.
Regards,
