This guide can help from a top level:
https://www.renesas.com/ja/document/gde/rz-family-product-part-number-guide
(note: not all the latest SoCs are in this guide yet)

However, there is no definitive guide as to which SoCs share the same IP blocks.
A lot is shared, a lot is not shared.
We do our best to reuse drivers for the same/similar IP as much as we can :)

Kind regards, Chris
