I fully agree with the risk that certain ideas will be overused. This leads to unnecessary complexity. I also remember the times of the GoF book and the design patterns rage.

The ideas behind those architectures require time to think through. The sooner you start, the better. Then, slowly, try adopting them. If you have a side project, then apply it over there.

It's crucially important to have a common understanding of the project within a team. The domain knowledge should come from the subject matter experts, but after that it should be a team work to decide which (if any) patterns and architecture should be applied.
