Honestly I would prioritize building the game using your natural (today's) intuition. I think you gain the best experience when you make mistakes and become intimately familiar with what it was like to write and edit a codebase with those mistakes, especially since you don't yet know what those mistakes are. Only then do you really internalize advice and better solutions because you can perceive the exact problems that the better code is solving.
