WandaVision was a very personal story about her relationship with Vision. If they discussed the Blip's impact on the world, I missed it.
I would have wanted something like apparently ended up partially on the cutting room floor of Falcon & Winter Soldier, showing us the chaos that resulted from everyone vanishing. Maybe do it as an anthology show, showing the surviving heroes trying to keep the world from falling apart between Infinity War and Endgame. End the first season with everyone coming back in Endgame, and then do a second, shorter season, showing how everyone is trying to keep things together once the world has to readjust in a hurry, including the very personal stories of someone reappearing in their home to discover their spouse has remarried, etc.
This is the kind of thing the comics companies love to do in limited series. I would have loved to have seen Marvel try something similar on Disney+. (It certainly would have been more interesting than Secret Invasion.)
WandaVision features the return of Monica Rambeau from the Blip and the hospital in chaos as people suddenly reappear (Monica also learns her mother passed on during the Blip). Monica shows the public chaos contrasting with Wanda's very personal trauma.
Hawkeye shows Yelena's Blip (as an instantaneous timeskip - indicating that those who disappeared have no memory of it) but she does respond to her loss by hunting down Barton
We also see how Hawkeye suffers survivor guilt and becomes the Ronin
Falcon and Winter soldier is all about post-Blip social and political fall out
Shang-Chi, Eternals, Wakanda 2, She-Hulk, DD and Echo reference the Blip as setting background.
(Interesting aside Banner-Hulk integration took 18 months in a Gamma lab that he and Tony built during the Blip)
Spiderman has its memorials, Wong became Sorcerer Supreme after Strange blipped, Wilson Fisk consolidates his power as Kingpin, Wakanda starts its Outreach Programme.
Secret Invasion is horrible, but Fury & Talos discuss the Blip and its impacts
So yeah, while I would love to see a proper Anthology of stories set during the Blip, its not like the Blip has been entirely forgotten.
And despite the chaos implied by the Falcon and Winter Soldier, it does seem that the efforts of Wakanda, the surviving Avengers (Okoye, Black Widow, Warmachine, Carol Danvers, Steve, Rocket) and various Government and NGO entities (SWORD, GRC?) helped to maintain a lot of worldwide stability. Indeed one of the Flagsmashers motivations was that the Blip had seen an emergence of global unity where nations put aside their hostilities and differences, opened their borders and created new communities.
