One thing that comes to mind off the bat is something which many websites (let alone Clubs) lack - and that is a comprehensive About page.
Personally, I find it annoying when I visit a site only to find that there is no page or section which clearly describes what the site is about or what it aims to do (what community it seeks to foster, what hobby/hobbies it focuses on, etc). I take the point that Pages is a formidable app with access and knowledge requirements above most average users, but perhaps a somewhat simpler interface is possible - as mentioned, something like Articles where pages can be added to a simple menu system. But apropos of my previous point, the ability to include widgets and feeds on these pages is something that would have a lot of potential for any Club. Clubs Enhancements has a "Home Page" option, and it's useful, but if you want to sex up your Club and make it more appealing something else is needed.
Not to mention that the more relevant content a Club has in pages (and elsewhere), the greater its potential visibility to search engines.
