So I'm pulling most of this out of my ass, but-
I think such an underrated concept to explore is Padme's first few years as senator. Like, just the culture shock of that alone must be enormous, going from Naboo and being the highest voice of authority to suddenly being just one of thousands (or hundreds of thousands depending on what canon you choose).
The slow creeping realization that Palpatine didn't fix any of the problems he told her existed under Valorum. Seeing just how deep and pervasive it really is. Realizing that most of her peers are only there for their own gain, that their priorities are themselves and not the people they claim to serve. That building, burning fury at the injustice of that. That she seems to be one of the only people trying to fix anything. Anger strong enough she could rip someone apart with her teeth that her colleagues are actively trying to stop her from doing that.
And that deep, alienating realization that she is so so alone in caring about any of this.
