I think it depends a lot on where you see this site going in the medium term (and in the website world, I guess that's 6 months to a year).

Joomla and Drupal will be fine for a standard architecture. If you're looking for something more complex or something personalized, they will hit their limits. So for example, the question is what you mean by "search for records from a list of 1000 to 5000 items"
