Various moon benefits:

- Relatively close and accessible (as opposed to the other planets)

- Seemingly stable platform to build, other wise we continue to rocket everything up from earth.

- Raw Materials - stuff to build more space vehicles, structures, etc.

- Lack of air - May help foster newer/cheaper materials and other processing

- Low Gravity - Also may factor into developing new materials and bigger objects.

- Lack of thick atmosphere - for astronomy, earth visualization.

- for data centers - potentially better cooling, or energy (solar) less susceptible to intrusion, security, etc. Lack of air might be a plus too.
