Grandtreks
I had Grandtreks for over 2 years on my previous 150 series Prado GXL and off road performed well enough. No complaints but having more aggressive tread (and height) would have been nice on few occasions so with new Prado VX decided for a change.
On the new Prado fitted Pirelli Scorpion ATR tyres in 265/70R17 size and happy with the choice. Off road Scorpions performs better than Grandtreks and also do well in the city.
As you are not planning to go totally bush touring on dirt tracks I believe Grandtreks should do well - just adjust your tyre pressures.

I got a mate who swears by them but i wanted to get a few more reviews.. i wouldnt say they are a cheap tyre seeing as ive got quotes for $250 plus at various shops.. im in the market for a new set now.. i had Maxxis Bravo AT700 and they are noisy they slide on dirt and mud theyve got no guts goin up a hill to be frank they were the biggest waste of $900 i ever had! PERIOD!!!

Well, had no trouble with the Grandtreks for 50k, including various gravel roads and heavier stuff.
Now I'm on Coopers STmax, and I worry less. The sides of the grand treks are very soft, not so good. The grand trek rubber is ok but e.g. Cooper AT3 which I had for a while is much better round corners and in the wet.2010 Kakadu. TJM T13 bar, TJM 9500lb winch, FJ Cruiser 17" rims with 265/70R17 Coopers S/T maxx, 40mm lift, Dobinson's C59-726, Bilstein shocks, Airtek snorkel, Recovery points, Brown Davies bash plates, TG150 transfer case guard. Rhino Pioneer Platform SuperPeg Rear Awning. Drifta Drawer System, Cargobarrier. Optima dual battery. GME UHF, Sandgrabbas.. ARB 47l fridge freezer.

I have had 3 sets of Grandtreks, 2 sets on 90 series for 170000K and one set on the 150 now at 65000K. Used them on most of tracks mentioned by OP as well as Gunbarrel, Gibb River road and Kimberley environs, Tanami, Nth East hills of Victoria and others. The last 4 years towing a small camper trailer. The occasional puncture mainly (only?) when tyre pretty worn. Also strangely most punctures were in built up areas due to nails and screws only a couple in the outback. Maybe would have had fewer with different tyres but who knows? I have a theory that maybe it is the softness that allows them to survive, certainly non of the chipping that is often seen on the popular LT types.
As others have mentioned tyre pressure needs to be adjusted to suit prevailing conditions. Deep mud? Forget it! Most other dry surfaces seem fine.
I had tools to repair and patch if needed and did practice on mine and other peoples flats. Not sure about the current 150 with its alloy wheels.
Coming up for new tyres now and not sure which way I will go, despite my good run with the Grandtreks I may go for LT's.

I travel fairly lightly and with appropriate tyre pressures and modest speeds and have had no tyre issues.
I know there is some luck involved.
I too have stopped to check on many well accessorised and very heavily loaded vehicles with the "preferred" AT tyres which were either flat on the bottom or had large sections of wall or tread missing.
As Dirty Harry once said, "A man has to know his limitations". I think some of my 'luck' is because I drive within both my and my vehicles limitations.

BTW I replaced my original Grandtreks at about 50 K. They were still in good condition for city driving but it seemed prudent to put new ones on before that horribly corrugated bit of road from Oodnadatta to Dalhousie to Mt Dare to Fink. A really crap bit of road.155 SX with dual battery and Polyairs in the rear springs..

Traveling light sounds good but how to achieve that? With a GX kerb weight of 2210kg plus 150l fuel, 100l water, 200kg passengers(3) body mass, roof tent, second battery, fridge, spares and stuff it is a scramble to stay below 3t GVM. But not towing helps, I guess.

................................But not towing helps, I guess.
I ran my Grandtreks at 22psi cold which was roughly 26psi warm.
Personally I think 80km/hr should be the max speed on any unsealed road you are not intimate with, a beautiful smooth unsealed road can have a lovely washout straight across it with almost no warning and the faster you are going the harder you will hit it.
Not sure how not towing helps keep the weight down in your Prado, one of the reasons I am a big fan of trailers is the ability to keep weight off the vehicle. Mine runs a tow ball weight around 70-80kg, but we store most of our camping gear, clothes, food, drinks, water, spares etc in the trailer, keeping the Prado much lighter than it otherwise might be.
