Criteria for Selecting Web CMS
I would focus on how content is created, how it's managed, how it's published or presented, besides the obvious cost factor (if any). Think about basic functionality. If you're doing website creation, how user-friendly and feature-rich is it? Consider indexing, SEO, customization options, speed. Does it have any user management options (roles and permissions)? Does it support versioning? Multiple sites? Multiple languages?
