For marketing pages, we usually pick between these options:
Wordpress is best suited for marketing site,
If you are building landing pages which displaying data from your app, we usually tend to prefer sailsjs.
If you have non developers contributing to landing pages, then wordpress is a good fit.
Being developers, we prefer the open source verion of wordpress. The open source version is more customisable. Also multisite can make this super cost effective.
Multi site is a bit more complicated than setting up the single site. If you are someone who is working with multiple products, then running multiple wordpress server will not be cost effective.
