I have an NCE PowerCab that came with a 1.36A supply but the power cab manual quotes a 2A capacity.
NCE describe the Power cab as "The Power Cab is a self-contained DCC system in one package. It is a Cab / Throttle, it is a DCC Command Station, and it is a Booster. All three in one package."

Am I right in my reading of this that it has a built in booster to take it to 2 A and thus allow me to run up to the 4 locos they quote?

The 4 locos limit come from NCE who use a rule of thumb that a HO loco draws 0.5A so they quote 4 locos for 2A.
As I only have 4 locos and not all will be running at the same time this is fine with me.
I also have an NCE "Twin" that I could use but do not plan to at this point in time.

The power supply is 1.36A - at 220-40V. [299W]  The NCE output is approx 16V - at 2A  [32W], plenty of spare power for the output.

Nope...
The power supply rating is measured at output, not input voltage. The power supply is around 20 watts. The PowerCab limit is around 25 watts.

OO/HO Locos run around 100 to 150mA on average - the figure of 500mA is way too high unless you are referring to O scale.

4 locos will be fine.

BUT - as your layout grows keep an eye on current draw. You should net expect long life if you run anything constantly at its limits

Woops, quite right Ahjay, wrong end of the Power Supply.   😊

Suggested power supply which also has better protection/top reliability. We use this supply with our own PowerCabs constantly
