Have you ever had to defend your decisions and approaches to a team or management?

Yes, such situations have occurred. It is important to justify the choice of solutions based on technical data, experience, and project requirements. For example, if I selected a particular library or approach, I would provide examples of its advantages, compare it with alternatives, and show how it affects performance, support, and scalability. This approach helps to convince the team and management, as well as find compromise solutions during discussions.
