For real though, I think a big part will depend on the roll of the dice. What tech cards you get, whether to delay teching to do research project or situation log things instead, how close you are to other species (making sure you don't get boxed in), what FTL type you have, etc. Besides the basic find planet -> colonize planet, find resource -> mine resource, there isn't really much else you can strategize for.
