So I think some of this might be overthought in this thread.
Best I can remember from various statements made by officials is that the actual Netflix shows themselves are not canon in Earth 616, but alternate earths, much like the Tobey and Andrew Spider-Man films.
However, 616 also has Kingpin and Murdoch (and likely others) who will be played by the same actors. While some will not. Like Kingpin's wife is already a different actress.
As far as these last few trailers, again, a bit overthought. Why is Kingpin mentioned a lot more than Maya? Well likely because 1) Everyone knows and loves Kingpin and he seems like he'll be a major character and unless you watched Hawkeye, you don't know Maya, so focusing on this is a better means of marketing and 2) because Maya does not speak verbally, and much of this stuff is voice over. So you obviously can't have her do any of that. Again, it's just marketing.
As to why the newest trailer has so much from the Netflix shows, I dunno. Could be 1) that 616 had a similar history but not identical to the Netflix shows and those are the same in both universes or 2) they just also wanted to advertise the arrival of the Netflix shows on Disney + and didn't really care about canon.
