In the interests of development speed, I don't want each member of my team to similarly repeat his research and analysis.

I'd expect of my team members to have encountered such situations many times in the past, and have done the research and analysis long before being hired. For junior programmers, I expect them to do the research once they encounter a situation for the first time, and remember them. It's called experience.

Now, there maybe situations that require different solutions for different projects. But you cannot both follow a company wide coding standard, and use a different solution each time.
