One unwritten trade off that's in addition, not a knock on your stance just an observation, is that teams that build one quality product can often build another. To some extent when you choose to build you are also choosing to build a culture that knows how to build. So you have to think about not just the next thing you need, but the five things after that. I've worked at companies that bought literally everything, and what I found is the engineers there knew a lot about how to plugin to these various systems, but when they needed to build something complex together they weren't able to do so very well, or at all. Which might be fine, but you should head in that direction with intention.
