Happy to help you with this, As per my understanding its bit hard to find an app which do exactly the same you have drawn. But the positive is that, this thing can be achievable with some customisation and coding that can give you the exact same results,
Here is the wire frame: A page(form) with the products you want to be listed- 5 or 6 as you shown in the diagram
Then a way to select the products, And adding those add to the cart once user completed all the selections.
You can reach out to me on the email below if you need more help with this.

This is an accepted solution.
Nick here from Shopify. Firstly, thank you for the time and effort to draw this out. It's very helpful to get such a clear and detailed vision of what you're looking for!

I'll put them below so you can see.
For the page structure apps there are two main ones I like:
Let me know if anything along these lines is what you're aiming for or can do what you want it to? If not, then I think @satsinghrana and @AiTrillion are correct and this seems like it might be a full customization. In this case, your best bet would be to reach out to a Shopify Expert to work with you on this. You can see the Expert Directory here.
