Algorithms and datastructures form the tactics of software development. your question is related to its strategy. Before you can master it, you first need to learn the concepts that are involved there. Don't buy books on methodologies, they are snake oil (I would love to be proven wrong by HN). The one book that stood out for me was this one:

Component Software: Beyond Object-Oriented Programming (Clemens Szyperski) https://www.amazon.com/Component-Software-Beyond-Object-Orie...

It's not a guide on how to do it, but it explains the ecosystem and forces in play (like why good components get rewritten, while bad ones persist). Once you understand these things you will have a better compass.
