Depends on how needlessly argumentative your team is. Generally you can reach a consensus through discussion, example and experimentation. We do have intuition, generally we know what simple looks like when we see it, likewise we recognise what the right tool looks like as we try several. Do you want a checklist for this kind of thing? You’re not going to get one. You have to use your own judgement. Possibly you’ve fallen victim to being on teams where ego dominates, and members refuse to seek the best option unless they came up with it themselves.
