Pex itself can handle more pressure, but taking into account the fittings and clamps, I'd set for around 50 psi. Many pumps give 40-50 psi, not many much higher, so may be considered a safe psi indicator.

This. My TT, which does not necessarily have the same limitations as yours, clearly says in the owner's manual, that 80 PSI is the absolute max it will tolerate. 45-50 psi, is a good safety margin, and is a range that household systems commonly operate. That's where my regulator is set, and you likely can't go wrong at that.
