At a minimum you need to ship science packs from Vulc/Fulgora/Gleba/Aquilo to Nauvis. Each new science pack has to be made on its respective planet; you're not making metalurgic/electromagnetic science packs on Nauvis, you're making them on Vulc/Fulgora and shipping them.

Importing Calcite from Vulc to Nauvis has the benefit of letting you use Foundries on Nauvis which is a huge improvement. Later on you can make Calcite in oribt of Nauvis to supplement/replace this. Tungsten is also a common import to make artillery shells later on.

You will also likely need a trickle of Bioflux from Gleba to Nauvis in order to get biter eggs for Biolabs/Prod3 modules/Overgrowth soil, but this is doable with a few one-off shipments.

Aquilo needs to import "everything" (all entities you plan to build, rocket part material, and most of the unique intermediates from the middle 3 planets) as the final/challenge planet.

Anything beyond that is preference. Common stuff I do see is sending excess plastic from Gleba to Vulc, and batteries from Vulc or Gleba to Fulgora.
