Remote Mining is very cost effective if you have a construction ship with one satellite launcher. Build a Large Sat with the desired mining component. You can make good use of Asteroid systems.

Remote Mining is very important in games where you can only colonize the right gas type (e.g. O2) or only the right Planet type (e.g. Gas giant). It allows you to get something out of all the other planet types. In these games you can make user of Base Miners where there are moons and planets in the same square. You colonists build a base to mine the uninhabitable moons or planet.

If you have very low maintenance, mining ships are more cost effective. Bases even more so.
