The 4 Strings system has a lot of potential for life and colonization, starting by its 4 earth like worlds, including a close-orbiting pair:

Additionally, a notable number of 6 terraformable high metal content worlds are also available.

Unfortunately the two water worlds are not terraformable, but still provide welcoming views:

Another interesting information about this system: it's part of a 90-system boxel that has just 5 ELWs in total, meaning it contains 80% of this boxel's ELWs.

With all this richness of life, one question remains: at about 9kly away from the Bubble, will anyone ever attempt to colonize it?

Systems which house four Earth-like Worlds are extremely rare: only five are known as of 3309/05/12, including this one.

There are five stars in the system, each with their own assortment of planets.

The first one is a class A blue-white star, which has a number of planets. The Earth-like world around this one (A 7) is quite hospitable, but the other planets have extremely hot and thick atmospheres.

The second star has two Earth-likes (B 3 & 4), as a close-orbiting binary pair:

For some added variety, the fourth Earth-like World in the system, DE 4, has a landable rocky moon of its own.

Additionally, there are six terraformable High Metal Content worlds around the various stars.

Lastly, there are two Water Worlds in the system, which are unfortunately not terraformable. Still, they provide some welcoming views, with their atmospheres (Ammonia and Nitrogen, respectively) shifting the colour of the blue oceans:
