By human-centric, it means exactly how it sounds: having humans as a central interest, influence, subject, etc. The leaks mention on multiple occasions about how the game will be "finding a home for humanity", "determining the fate of humanity", etc. It makes it sound like humans are the center of the universe, when that shouldn't be the case in Mass Effect where humanity is part of a community. It has nothing to do with sexism, racism, or social justice. The Shepard Trilogy was full of this, and many players didn't like it and/or found it ridiculous. Things like humans are the most genetically diverse race in the galaxy(we aren't even on our own planet), or how humans are the best candidate for making a Reaper Dreadnought, or how everything should be dedicated to taking Earth back, or how it is human DNA that is needed to save the universe and reach the peace Reapers have been seeking. The only time it made sense to be human-centric was Mass Effect 1, because it was about humanity earning its place in the galactic community. Once we earned that place, any human-centricity should have stopped. But instead, it increased exponentially and is continuing in Andromeda, despite all races being in the same boat both literally and figuratively.
Okay, you've actually peaked my interest now. I think you have a point but I think you would have to start by agreeing that this idea/issue you are bringing up 'human-centric' is really just analogous to our own race issues from the past millennium.
I say this because what you are essentially bringing up is 'humanism'. And if we discovered alien life, there might be a new word created that goes something like 'lifeism'.
IE, all life is precious/sacred, all life should be preserved. Therefore, one race/species shouldnt consider their own interests above another for said reason.
The metaphor/analogy you present is that this is similar to say a white people thinking they are better than 'insert colonialized race here'. I dont want this to span into a SJW versus 'why should I have white guilt' issue, lets just all agree that **** that happened in the past sucked and focus on the parallel with the game here.
This question is actually incredibly interesting. I've never done any subjects on ethics/morality etc, and I've read only the beginnings of content on philosophy, but if you were to say propose value between a Krogan life and a human life, (and not one of your Krogan pals you've managed to convert to paragon, but your average krogan), a Krogan who thrives on bloodshed and at one point wanted to conquer the galaxy for the sheer love of bloodlust, you raise an interesting discussion about whether humans SHOULD consider their own interests. I would sit on your side here, the 'paragon' side of 'humanism/lifeism', but I would not necessarily blame somebody for not valuing the life of all Krogans over the rest of the galaxy, and making that choice in the game. A harder choice still would be the Rachni.
----------------------------
With all this said, IMHO The renegade option should be victory at any cost. As you are playing as a human character, your choices will be largely self-serving and human-centric. In my opinion, this should be at stark contrast for your desire to see humans being nice to other races because they hold that set of values. If your desire is that all video games or movies are all sunshine and lollypops and you never see the greedy side of humanity then in my opinion you have poor taste in literature. When you explore renegade, greed should play a factor.
However, the paragon option should most certainly hold the values you are talking about and not be 'human-centric' as it wouldnt be very paragon. So the question is, does the paragon playthrough of ME1-3 correctly reflect a 'all life is precious', view of morality as opposed to human-centric?
From a quick recap, I would have to conclude yes;
- Save the council despite them shitting on you
- Save the Rachni
- Save AI that were created by the Quanari despite them being a machine based life
- Save the Krogan despite them wanting war, give them another chance
- Need I go on?
I mean, to me I feel like you are doing some serious projecting on the game here, because to me the paragon play throughs seem to be very much a 'good of the galaxy not just humanity', plot theme. Everything about paragon is literally your contention, that all life/races are sacred and should be protected... the greater good.
If you are angry just because you CAN be greedy in the game, then sheesh man, boring.

Also, like it or not, the game is entirely fictional. So for all you know, humans COULD be superior in this fictional world created, as per all the items you listed out. IMHO reason you find this 'ridiculous' is your desire to normalize the human/alien issue debate against your projection of our own human/race issue debate. In reality, due to genetic diversity, if we encountered aliens its quite likely that we would either be smarter or dumber than them. The fact that the aliens in ME were so normalized in terms of intelligence was actually a flaw in my opinion, not the other way around, and it was done as a narrative device so we could have the best interaction with them and the game COULD be an analogy for race issues.
