Check the video I linked on my reply to your post in the fist page. It should help you solve that.
In Nikon there is more than one setting you have to change for BBF.

There is actually only one menu item you have to change in the Nikon menus and that’s is AF Activation. There are others things you can change but setting that to AF Only is the only change you need to make.

I think this depends on the model. I remembered there was more than one setting, but I think that is the case if you have no AF-ON dedicated button, because the other change is assigning a button for BBF.
Thanks for correcting me!

You’re mostly a landscape shooter. Start shooting wildlife and you’ll appreciate BBF.
I shoot with Sony, they have what is called, Tracking expand flexible spot, once your subject is selected, you push your SHUTTER button half way and the tracking keeps the selected subject in focus, and I can now recompose all I want, the selected subject stays in tack sharp focus, the exposure changes correctly automatically, all with the half push of one button. Now I can use the button for BBF for what is more important for me for shooting wildlife. Thank you Sony. Isn't technology great.
And, if you like BBF, by all means keep on keeping on.

In an Nikon camera, activating focus with the shutter button acquires focus, but does not lock focus - recomposing with the shutter button half-pressed will re-acquire focus. To lock focus you have to use the AE-L/AF-L button to lock AF. You can program the behavior of the AE-L/AF-L button to lock either AE or AF or both using Custom Menu Setting G3 (on a D800/D810). You can also do AE-L using the shutter button using Custom Menu Setting C1, "Shutter Release button AE-L". You can also assign the Fn button with Custom Setting F4 to lock aperture and shutter speed if you like. Different Nikon cameras may have slightly different menu settings and controls, but they tend to be similar.
Using back button focus with the focus on shutter deactivated allows you to only focus when the AF-on button is pressed, so releasing it allows you to keep the focus at the current setting, which allows you to recompose and shoot without reacquiring focus. No pain involved, just teaching your thumb and brain a new use.
Keep it simple - you might be overthinking this.

Gene, great explanation.
However, this behavior that you describe in the first sentence only applies if you are in AF-C, right?
I think that if the focusing mode is AF-S, then half-pressing shutter and keeping it pressed will keep focus locked (with default camera settings).
As usual, I may be wrong :) That happens more often than I like
