If you haven't read it already, you might enjoy the Culture series[1] by Iain Banks. It's sci-fi about a Culture of humanoids that have effectively mastered the galaxy, and they have GSVs (General Systems Vehicles) which are huge spaceships that effectively carry all of the Culture's knowledge and manufacturing capability with them wherever they go.

As an additional side note, many of the spaceships in the series are sentient and have interesting names, two of which SpaceX used to name their own drone ships.
