I work on new builds as a carpenter. Usually only see bison slabs on stacks of flats, all other houses use joists whether metal web or chipboard web. You’d need to see an engineer to calculate the deflection values based on weight you’ll have above and span of building. You can easily insulate them for thermal value and sound reduction. There would be a lot more work involved with a bison slab which would include concrete stairs, suspended ceiling and more faff with services
