p-channels are somewhat more difficult to produce. And therefore more expensive.
Using an N-channel only requires a voltage booster, these are available in small IC's nowadays, so the threshold of getting high-side N switches is not as high.
You can even get smart high side switches (or powerpath controllers if <5V), which are basically n-channel and driver circuitry integrated. Infineon has as lot of these. They're nice because some have feedback circuitry and automotive specifications. Bit more expensive though. But nice as low current solid state relays.
Compare some n-channel with high-side driver combo's, versus p-channel fets. And see what suits the design best. Probably p-channel in your case. If you're not running a lot of amps.
