Older multi-family inventory drives steady attic top-up and air-sealing work, and the Filipino-American community concentration shapes a long-tenure owner-occupied dynamic that supports the energy-ROI conversation on most projects.

What STC rating should I aim for?

Code minimum for shared walls is STC 50. STC 55 starts to feel quiet between rooms; STC 60 is what you want for a recording space. The pro designs to a target STC, not just to a product. Mineral wool gets you maybe 4 to 6 points; the rest is mass, decoupling, and sealing.

Will mineral wool alone soundproof my office?

It helps but it isn't the whole answer. Most noise comes through gaps, doors, and flanking paths. Plan on sealing penetrations, gasketing the door, and possibly adding a second layer of drywall with green glue. The pro designs the whole assembly.
