The confusing part of looking for the right web platform is the terminology. SITES are literally universal across any CMS whether that is a 1 page or 10 page. Obviously the differences are in size of site and goals to be achieved - but essentially the structure is the same. A thoughtfully robust platform that takes into account the different use cases you will encounter is where a product manager should lean.
The reason: managers want their teams on a central platform that handles all types of client solutions while not switching between 4 - 6 other dashboards.
One small note - features may seem cool - however if they do not align with the strategy or use case what's the point? Pick a vendor that demonstrates your specific use case utilizing their platform - then make the decision.
