I don't know at which stage of the design process you are.
Since you have, already, some UX Key Performance Indicators (KPIs)
I would start making them visual within a draft of the home page.
I would start to make a lo-fi wireframe to check:
- type of content (text, images, rich media etc)
- the amount of information (web forms, menus, lists etc)
- the number of interactions (tap/click to open/close, tap/click to access a specific information etc )
Once you (and your stakeholders) highlighted PROs and CONs of the proposal, it will be much easier to find, one or more, good benchmarks to start with.
