I intend to buy a 16-inch MacBook Pro and it comes with a 96w USB-C Power Adapter + USB-C Charge Cable. Do I also need to buy separately a POWER ADAPTER EXTENSION CABLE?

Only if you want the extra length to reach a wall outlet. It is basically just an extension cord. I had one with my previous MacBook Air (they used to be included but no longer are) and never used it.

I always liked to be plugged into the grounded plug,

and the grounded plug into a surge breaker.

Why risk the expensive electronics to dirty electric, brown out or surge in the power supply for any reason.

The two prong duck head is not grounded.

Apple used to supply the ext w/each new Mac, not any more in cost cutting. They are interchangeable.
