Pretty much, but it also needs to be said that Suzaku's intentions of reforming the system from within were always looking towards the long or medium term. His chosen path demanded a lot more personal endurance, tolerance for bigotry and patience in the face of oppression than Lelouch's. I feel the series established this well enough.
In a different kind of story with either a realistic pace and more episodes or even just a bunch of time skips to make up for it, the entire process could have taken several decades and there's no telling that Suzaku wouldn't inevitably become disillusioned with the system first. That's not much of a Code Geass-type of narrative, but I'd still watch it.
The biggest obstacle to his ideals is that as a member of the military and an Eleven, Suzaku has no direct power to enact any changes by himself in the short term. He needs to gain the cooperation of nobles and high-ranking figures, most of which aren't going to give him the time of the day.
After Euphemia's death, which closed the door on an unexpectedly peaceful compromise, Suzaku got understandably angry and just went right back to thinking that the only remaining solution was continuing to climb up to the top of the organizational ladder at any cost. He wasn't going to get promoted into a position of authority if he didn't shut up and enforce the rules, which means there is little room for ambiguity or skepticism left.
Granted, I would have liked to see the series give more importance to these sorts of political topics as time went on, instead of pushing them to the background, because even when Nunnally comes around to mess with Lelouch we never see enough of what she's doing nor of Suzaku's limited non-military activities.
After they controversially reintroduce the SAZ, it's implied that Zero's one million man stunt made such measures look weak or pointless, but there's no elaboration. Suzaku goes around doing a little bit of off-screen paperwork but he -and the show- is more obsessed with the fight against Zero than anything else. The first season wasn't quite perfect in this respect, but I believe it tried to go for a more balanced approach nonetheless (aside from the ending).
