It was specifically noted that items he summons can be used regardless of normal proficiency limitations. He can even cast a few of his spells while burdened with his summoned full plate armor, (despite having no armored mage type classes like Narberal), but it hasn't said which ones to my knowledge. (Flight is at least ruled out, since he had to use an item to view the sky with demiurge). In the fight against the workers in Nazarick and clementine he was not using Perfect Warrior, else he would have mopped the floor with them. He was specifically testing the limits of what he could do/learn regarding fighting now that he's in a new world. He may have had Perfect Warrior on when he sparred with Parupatra and others though.

As for Cenderlius, Perfect Warrior is obviously inspired by the DnD spell Tenser's Transformation. That spell for reference leaves the caster unable to cast spells for the duration, in exchange gaining some physical stats, weapon proficiencies, and raising the base attack (the stat that determines both number of attacks per turn and a large part of accuracy) to that of a warrior, i.e. full. All these benefits disappear at the spell's end, and the flavor text for it says that it changes even the mindset of the caster. Given what evidence the novels have provided, I think the same occurs for Ainz, that not only his stats, but even his form improves, but only while the spell is on. I cite that he said he still felt anxiety during fighting after his bout with Hekkeran's worker team when he clearly didn't have the spell on.
