This will probably be an unpopular answer, but if you are in a situation where you need to turn over management of the site to a team of non programmers (which this post doesnt sound like); Managed Wordpress + static site plugin and cdn caching.

Managed Wordpress hosting is $4-$6/m from a reputable place[1], and then everything wordpress and below needs no maintenance. Youll have access control for which team members can control what, and there's probably more wordpress expertise out there than any other platform. The amount of good plugins out there minimize reinventing wheels.
