Early on (first year), building a stack of 3-4 SY bases will help a lot.
You can pump out ships much faster that way.

Any planet that has excellent value in organics or rads should have some extractors of that type, even if you don't need them. Either you'll need them later, or you can scrap extractors on a multi-resource world in order to make room for more mineral miners.

When building monoliths, it is best to fill up the planet with regular miners first, then build one monolith and scrap one extractor at a time to change the planet over to monoliths.
Regular extractors can be made much faster than monoliths, and you'll harvest some extra resources while the monoliths are under construction.
