I didn't have any RFI problems in my own shack - mostly because I'd already fixed my own pin 1 problems.
All the problems were with the neighbors' equipment, where the only practical solution is to reduce the RF current it has to contend with.
There is no conflict here. The ground path for all unwanted currents - be they lightning or RFI - should be through the ground bonding outside of the building. We specifically do NOT want any fraction of that current to be grounding out by passing through our equipment and the indoor mains ground.
For safety at 50/60Hz, I strongly recommend using a commercial mains filter that is liberally covered in approval stamps. If the ground connection through the filter satisfies all those paranoiacs at UL, TuV, BSI etc, then it's good enough for me too.
