I highly suggest WordPress, heck it's good enough for The Huffington Post and The New York Times. If you need assistance, contact me.
Yup, WordPress for sure. We've been running on that for about a decade. It's very easy to use and extremely flexible. Tons of themes already available or you can make your own, of course, but honestly that is a waste, just buy one or use a free one. It is backed by MySQL and can scale like crazy. And it is very easy to front it with a CDN like CloudFlare to make things even faster and safer.
And deployment guide available that makes it super simple: https://codex.wordpress.org/Installing_WordPress#Famous_5-Minute_Install
Run it on a LAMP stack for best results, IMHO. CentOS 6.5 is my recommendation. Everything you need is available via YUM (except WP itself, of course, although I hope that they include that in the future) and works together immediately.
