I agree with you that Pulse CMS offers an interesting way to go, without databases. Before moving all my sites to WP over the past two years, I had always felt reluctant to use databases: but testing WP had convinced me to go ahead. Although I do not use it at this point (I played a little bit with previous versions), I bought a Pulse CMS license, if only in order to support that interesting project. I do not rule out using it for a site some day, at least experimentally.
Although Craft CMS is not that famous, it is extensively being used by Netflix and Salesforce websites. It is developer friendly due to its extensive back end features for your application. It does not provide any front-end themes. Unlike WordPress, it does not have a predefined content type and hence it allows the user to set up their own content by making use of 18 different types of fields. It provides user view to the admin console and also enables side by side changes that they can make. The admin can create groups that can help in restricting or enabling different users from accessing some specific features. It supports different environments which can help in creating site locally. It deploys to staging and then to production. The flexible fields can also help in creating perfect interfaces with complete developer control.
