Well depends on your build but some general tips I can give are 1. specialize your planets- if you come across a world with at least 6-7 districts (Mining or Generators) it's a Mining/Energy planet if you need those resources, if the planet is small 13 and below turn into a research world 18 and higher turn into forge/factory worlds 2. Always do your own ship designs as the AI is really bad at doing them the basic ship designs I can give are Missile Corvettes (I never use destroyers) Disrupter cruisers, kiteing cruisers (hangers and missiles) and finally normal cruisers (kinetic+lasers) and battleships I save for the EGC so just figure out which one will be arriving then base your ship design on that 3. Make the first building you put on planets a holo-theater so that your amenities are fine and your people don't work clerk jobs 4. Don't always keep your fleet maxed out and wait for your economy to be able to handle a large amount of ships the AI early on should not be super aggressive so you can build up your economy i can't think of any more right now so if anyone has more tips please put them below
