For a pretty great introduction on how to structure the FE of a web3 app I would take a look at PancakeSwaps GitHub, they have open sourced almost all of their code and it is pretty well written.

Many projects start as clones of that repo.

As far as use cases are concerned the best source of information has been and always will be the community itself.

All reputable projects produce white papers and they are usually more than happy to discuss questions and concerns in their community discords / telegram.
