If only there was a clear answer to this. Software engineering, as it has appeared to me, has always seemed to evolve with opinions moreso than tangible improvements. That being said, some practices are almost universally agreed to lead to better code, like defensive programming (proving your assertions relating to program conditions in the actual code), uniform documentation, and, in general, taking your time in implementing structures that will be used throughout the codebase. Formalizing your logic in proofs can be one part of that.
