IRF9540 is a very good MOSFET. 150W and TO-220.
Here is shown a load of 5A with only 0.48V drop.
R1, C1 and D1 provide a start impulse for the regulator.
The regulator is variable 5-25V.

This voltage regulator keeps the output voltage very precise in all conditions.
Here is 12V input and 10V output across a 1A load.

You could look at the mic515x for a mosfet power supply driver for N channel devices. Some parts in that line up have a charge pump so you don’t have to furnish your own drive voltage.
I think using a P channel device is feasible, but requires careful stability analysis, most LDO devices using p channel devices are inherently more unstable than N-channel equivalents.
Mic5156 is a very nice chip for this application with guaranteed stability
