Hauling trading goods is always a staple of a space game, regardless of how annoying it may be (looking at you, SpreadshEVEt Simulator). There is also a trading system in FOTP.

And dedicated hauling ships.

One could use their normal ship for cargo hauling, but it’s probably better to take advantage of the gameplay only available to Container Ships like these, where the containers fly themselves to and from the station with the goods you want to buy or sell!
