What SEO factors do you consider when selecting a CMS?

[amastix]

I'm assisting evaluating 5 different CMS solutions for a client. As a part of this evaluation, I want to ensure we fully explore the SEO capabilities and short comings of the different platforms.

Which factors would you recommend we consider?

Currently, I'm thinking:

• custom URLs
• custom page titles, meta data, etc
• automatic sitemap updates
• customize robots/indexing settings
• site load times
• rel canonical support
• code & css quality
• 301 redirect functionality

What else should be on this list? Is there anything on my list that you would de-prioritize?

At risk of making this question too large: any opinions out there on what the most SEO friendly CMS systems are?
