These days, I use the Peak Design (PD) straps system which uses anchors on loop holes on cameras. As such you can change the strap to fit the body and lens combination as you need.
I have the Cuff (wrist strap), Leash (small), Slide Lite (medium), and Slide (large).
For example when I use the D500 with the 70-200mm f2.8 VR I use the Slide attached to the right and there lens tripod collar screw (without the foot) via a small plate. I sling it on my left shoulder across my body with the camera either to my right side or behind my back. It is comfortable and secure. My hands are free but still I have quick instant access to it. And also I can move freely with minimal camera swing.
It is also discreet; people are less threatened by a big camera that is not in your hand.
When handling the camera at home or storing it in the bag I can take the strap off easily because of the quick release anchors.
And when I need itto be on another camera body like on my D850 I can swap it out straight away.
All anchors are rated at 80kg maximum load. This is more than enough when my camera set up is 3kg at its heaviest. The rating overkill gives me a peace of mind.
The price for PD may seem excessive but seeing that your gear is worth thousands if not tens of thousands of dollars the cost is pennies for security and reliability.
The other straps like the Slide Lite are equally good for a smaller set uplike the D850 with 24-70mm f2.8 or with prime lenses. The Leash is good for compact cameras and light SLR/DSLR set ups. And when I need a wrist strap for quick lively action then there Cuff comes in handy.
