And secondly, why would he use anything less than his most powerful form to fight, especially since he was fighting for his life and Toneri already oneshot him before?

He used SPSM to fight the Shin on several occasions, and those weren't exactly Toneri-level enemies.

From what we know and have seen, he needs his full power to traverse dimensions and can decipher at least some of the stuff she's left behind (Sasuke mentioned he couldn't read the scroll in a way that implied he could read other scrolls. I doubt that after 1000 years, all Kaguya left was a single scroll, especially since nobody else has touched her stuff).

There's no indication that he needs his Rinnegan to sense some mystical presence, so there's no point to keeping his Rinnegan active for that. If he encounters some other temple or scroll, he can simply activate his Rinnegan, assuming that he could. There's no reason to have it on all the time for the offchance he happens to see a scroll.

Especially since the Sharingan grants the ability to analyze everything he sees no matter how fast, so if he couldn't miss a thing, why not keep his Sharingan active too?

It just makes no sense. So it seems to me he normally can't deactivate his eye.
