The old leak (which has been essentially confirmed by subsequent official information) suggests we're making the sort of decisions that only a high ranking leader would make. Picking our missions, establishing settlements and so forth.
Fundamentally, if we're not in charge then there doesn't seem to be much sense in all the "exploration" stuff. We'd just go where we were sent.
Could be a necessity thing, could run into hostile aliens pretty early meaning some people either taken out or we're just spread so thin it has to happen. We also don't really know when it happens, could be something they build into early on showing why/how/etc so you have something to react to. Hell, if it's mostly exploring, and since no one has experience in this sector of space, they may not really care so much who's leading as it gets done. You could even be taking orders initially until you show that you can hack it. If the rest of Ryder's family is present you could be working as a team with them + all your normal companions.
So basically everyone in this thread assumes the journalist was wrong.
Or that we do what we do with all incomplete information, we question and try to rationalize it.
It doesn't explicitly say they're all young. Young is also subjective, you place so much emphasis on them being in their 20s and hating it especially when you aren't even out of your 20s yet. I don't see what's wrong having a younger team and without more concrete info we have no way of knowing the age ranges....and they shouldn't even matter if the story is good and their characters are good.
So, yeah, we know they have a "younger cast," but we don't know anything beyond that and it doesn't preclude older characters.
