I don’t consider flexible things to be a great first choice when making certain kinds of tech decisions. Instead, the simplest way to get started on a new technology is to use opinionated things. These are tools, languages, and frameworks that accomplish the same thing as their flexible counterparts, but in a prescribed, specific, dogmatic way. They are relatively easier and faster to get started with, and simpler to work with as there is no real debate about how things should be done, just get things done. Over time as the stack and the teams grow, they can learn what their requirements and needs are, and finally gain greater confidence in the decision making behind future things, including very flexible things, or continuing with opinionated things.
