I think for this, it's absolutely appropriate to compare to other solutions on market. Even the official Pi foundation data sheet describes CM4 as for "deeply embedded applications".

I would also recommend to carefully examine low-cost x86 options, they often do come out ahead given they usually include all the stuff the Pi Foundation don't supply you - a boot volume, case, power supply etc.
