Currently probably biggest advantage is electric car charging. It is easy and cheap to add high power fast charger when there is already 3 phases available.

400V between phases so 230V per phase. Safety is provided by making plugs not expose contacts while half plugged. US plugs are really unsafe compared to plugs used in most of the Europe.

And safety provided by having much stricter control and requirements on the whole house electrical system.

Also power tools, with 400v plugs you can go to much higher wattages on circular saws, planers etc.
