There are a few plugins like Wysiwyg Editors, Static Pages, and Content Editor which can help bring your platform closer to WordPress. I have used one of these for numerous clients.
Though I have gotten to the point to where I have started making my own front end plugins that allow my clients to create, update, and delete pages. Add them to a menu etc. They can choose the layout, add sidebar(s) content and images. The plugins are all unique depending on what the client wants.
I think this is where OctoberCMS shines for developers and ultimately for your client. They don't need to be overwhelmed by everything in WordPress. You as a developer create a system (and hopefully foolproof it) that the client needs then hand it over to the client.
