The power Starfleet has on civilian, matters is pretty scary. A military should not have the power it has.
What powers are you referring to? Because the worst that I can recall that we've seen is that apparently, per DS9 "Let He Who Is Without Sin...," Starfleet officers are legally empowered to act as law enforcement in certain scenarios. That may be questionable in terms of whether it's a good idea in principle, but it's not clear what those exact circumstances are or what limits they have, so I really don't think it's enough to label the Federation as dystopian.
Not to mention the corruption at the top. Ever other admiral seems to be corrupt or insane .
And almost all of them seem to be thwarted in their evil plans, which already means the Federation is doing better than most real-life societies.
It might be bright shiny and have a high standard of living but it has a lot of rot in it.
I dunno, I feel like you've enumerated reasons for why the Federation is a society with problems, not reasons for why the Federation is a dystopia. Like, a dystopia is not just a society with problems -- it's a society that is fundamentally tyrannical and/or fundamentally broken. Even at its worst (the period from 2385 to 2399), the Federation was not fundamentally tyrannical or fundamentally broken.
The only time I think you can make a half-decent argument for some level of dystopia is the chaos that followed the Burn in the 31st Century. But even then, I don't think
dystopia applies except in those worlds that left the Federation and came under the thumb of the Emerald Chain. It wasn't the Federation per se that was being dystopian.
Then there is the fact a dozen Borg cubes could jump in any time and assimilate everyone. The federation was lucky they were low on the priority list.
I mean, sure, but the potential for imminent destruction is something
every society has to live with. That's not dystopian, that's just life.
