W3 Total Cache + Hummingbird + Cloudways (Varnish Cache / MemCache Enabled)

Good evening. I am currently looking at enabling W3 Total Cache for our website. We use Hummingbird for minification and Cloudflare integration. Our host, Cloudways, offers Varnish Cache and memcache functions. Should I enable more cache through W3?

Any help would be appreciated.

Thanks,
David
