the IRLD024 are a bit expensive, but that's less critical for prototyping, where a smol package that fits easily onto your breadboard without wearing it out can be really fucking convenient. not strictly necessary
the IRF9540 is a P-channel complement of the non-logic level IRF540. that's probably okay for switching high-side loads at 10V or higher where your low-side level shifter can be made tolerant of the higher voltages. the IRF9540 should also work well when driven by 5V CMOS logic levels and Ids requirements are only 1A or so
