Automatic On Demand 4x4...is it worth 10 Benjamins?

As far as I know Jeep and Toyota don't offer a full time AWD system in the states.
Most manufacturers use either selectable 4wd (4Hi, 4Lo, 2wd) like the standard Bronco Tcase, Automatic AWD (Front or rear wheel drive until slippage is detected), or a combination of the two like the upgraded Bronco Tcase.
Subaru, Audi, perhaps some of the other German manufacturers, are the only full time (front AND rear wheels powered ALWAYS) AWD system users that I can think of. Focus RS was I THINK.

I guess for some reason I was assuming that the Advanced 4x4 with Automatic On-Demand Engagement was something that would come standard when you option the 10-speed auto similar to the trail control and trail turn assist. Also looks like the one-pedal driving comes with the 2.7L. Looking at the website now I see that the Advanced 4x4 is not dependent upon either the 2.7L or 10-speed options, or at least it doesn't come out and say it. Now I'm concerned about how much that option is going to cost.
on my Renegade, I usually turn off all the traction control settings with 4x4 on, especially in the snow. It's more predictable to me.

I use 4A in my F-150 pretty often when I’m driving like an a$$hole. Whether it’s trying to race to a merge or driving too fast in the rain, it has come in quite handy.

Focus RS used the GKN Twinster system, which was also used on several other models include the Land Rover Evoque.
Surabu uses several different styles of AWD, some of which have a mechanical/viscous f/r torque split, and some use an electromagnetic clutch to vary front/rear split. The second kind isn't really any different from the common Haldex that uses an electromagnetic or fluid clutch to transfer power front to rear.
Setups like the Twinser, Audi's Sport Differential, BMW's active M diff, and a very select few Subarus can actively transfer power side to side. The vast majority of Subarus just pulse the brakes on the slipping wheel to send power to the other side. The aforementioned diffs typically have clutches on each axle that can actively vary lockup and move power as needed.
I'd say a system that is actively sending power to all four wheels 100% of the time is a huge disadvantage to a vehicle. Making it driver-selectable or condition-dependent provides a huge benefit to fuel economy, wear-and-tear, and drivability.

Somebody has never driven a first generation STi all locked up on the dirt!
In all seriousness, it totally depends on what you're doing with it. Personally, I don't sweat a few MPGs, I find modern vehicles to be quite reliable when well maintained, and the grip of actual AWD can be a HUGE benefit to driveability in certain (most) cases.
For the Bronco I feel the given choices to be most logical.
the current toyota land cruisers and lexus equivalents are still full time AWD with lockable center diffs and two speed transfer case. (most owners of said vehicles have never locked the center diff or actuated low range)

Yes, it's great because it has a driver-selectable locking center diff. It's not a lethargic n/a flat four wheezing into a CVT vaguely throwing power around like most Subarus.
And in the real world, the performance advantage of a "true" AWD system in a non-racing application compared to a "fake" Haldex system is almost nil. But the advantage of being able to "unlock" and go into 2wd mode is real.
Certainly.

Well, we were talking about AWD systems. Not transmissions or base engine choices
What is this "non-racing application" you speak of?
There was a whiff of "only Subaru makes REAL AWD" in your post, which is a dumb thing people on the internet won't stop repeating, because Subaru mostly makes junk AWD.
Something boring people do. I've heard.

Maybe its in the 7 pages somewhere, but lets start with how you assigned a price tag of $1000 to it. This is presumptive. My impression and feedback is that this might not be a stand alone option but included with Sasquatch but I can't confirm that it is stand alone a la carte or package deal. Was curious how you decided $1000

You mistake my arrogant correction of the poster's terminology for fanboism. I literally listed at least 3 other manufacturers of full time AWD systems. And never said "real."
While I am a fan of Subarus (the fun ones), I'm not a blind zealot. Although, one might call your classification of junk the opposite end of that same spectrum.
