I’ve tried it a few times and didn’t get it. Maybe this guy explains why:

Same here. Just another thing to fiddle with. To me, it's somewhat of a dunsel.
Some like. Some don't. I use the 1/2 press of the shutter. Less fingers involved with taking a photograph.

Stand like a BOSS!! Luv' it!!
~I've tried BBF over the years - It's not for me. Not for the reasons this guy says, however. It's just not my thing. Don't like it.
~Focus point where you want focus - SO important to me. I'm surprised that I have never worn out the toggle to move the single point sensor all over the place. I use that 98.5% of the time!!
~ Stand like a BOSS!! Yeah, most of the time I will do that. Sometimes it's not possible, but most of my better handheld shots come from that stance.
Good video IMO.

Depends on what you're shooting. If you do a lot of shooting of BIFS or other moving objects like sports (well when we had sports), etc. then BBF is the way to go because it separates focus fro shutter release and increases likelihood of getting the shot(s) you want. Once you get used to it the whole idea of pressing the shutter release button halfway, focusing, and shutter release seems much much simpler. If all you shoot are still lifes or landscapes probably isn't relevant.

That is why you camera has optional settings. So you can customize it to your liking.
Personally I like having focus and exposure decoupled, and on separate buttons, but that is me.

On my mirrorless I prefer to set the usual BBF button, AF-on, to instead turn off auto focus. I keep the camera in servo and tracking all the time, and use the button when I want to recompose with locked focus or focus manually with peaking. Two things you can't do in servo otherwise.

I have DSLRs and Mirrorless (all Nikon). There are great advantages with back-button focus and I can't imagine making an image without it.

Maybe you need to try the alternative to realize the benefits of using the half press method. The video described them.
Your post doesn’t assert any advantages of BBF.

Watched the first section regarding BBF and as much advice out there it is simply too 'generalised'.
Scenario using BBF;
Runner coming towards you, thumb on AF On (BBF) which has activated servo (continous AF). Finger on shutter button and half pressed to retain VR on. Shutter fully pressed at instant you want the shot.
There is only one movement at this instant which is your finger on the shutter button, there are not two movements involved as he states giving you less sharp images.

What is the advantage of that over activating the AF with the half press of the release?

Mirrorless is a whole 'nother world when it comes to bbf, because there are thousands and thousands of focus points directly on the sensor.

I'll continue from the previous scenario;
During tracking that runner coming towards me (using the focus point set and in continuous AF) I notice an interesting spectator/spectator group at the side of the road. Immediately I have taken the shot of that runner I quickly swing around and focus on the spectator, remove my thumb from the AF On (BBF) button (the camera is now in 'single' shot), re-frame and take the shot.
I can then immediately swing back and take another runner without spending unnecessary time changing between AFS and AFC or moving focus points.
With regard to your question the advantage is 'time' saved and correct usage has no detrimental affect on sharpness of image.
Start of scenario ..............
