I agree that Cards are the best Material Design pattern for the design flow you have in mind.
But before you settle on this design flow, I would like to challenge it with some usability questions:
Are you confident that your users will understand what to expect from the options "Planogram" and "Merchandising Activity" sufficiently to be able to pick the right option?
Is it imperative that the user makes an "either / or" choice at the outset? Or could you design it in a way that allowed the user to avoid making an up-front choice?
If any of these questions raises a doubt in your mind, I think you should reconsider your current design flow.
Assuming you are confident with the flow, however, I am attaching a wireframe with a couple of suggestions, as follows:
- Use Cards to present the binary options -- as per your own hunch
- Add informative text to the cards -- to inform the users what to expect
- Add a Universal Menu -- at this point, it may only allow the user to log out. But it also serves as an anchor, and on later screens, users may use it to return here.
