I’ve done further research, and even came up with a site comparison survey which listed the plusses and minuses of Drupal, Joomla, and WordPress. All the wisdom gathered so far adds up to this: they each have their own strengths and weaknesses. But nobody I have consulted yet has managed to persuade me that a normal human being can handle Drupal without two years’ training in a sealed room. That narrows it down to two – and since I’ve dabbled with Joomla and been defeated, I’m currently allowing myself to be persuaded that WordPress, although it started as blogging software, has now developed sufficient features and add-ons to make it a real CMS.
Next – can it easily be integrated with an eCommerce application, and can I use a Google search box on every page?
