Also, one thing I wanted to mention was the commercials. I feel the commercials are traumatic periods in Wanda's life that she is coping with.
#1 : The toaster represents a bomb. When Wanda was young, she, like most people, probably looked up to Tony Stark, since he was considered by many to be a philanthropist and innovator that would take the world into the future. Then her parents are killed by a bomb developed by Stark Industries, unraveling how she saw him and putting her and her brother down the path that made them who they are now. The toaster "ticking down" ominously, before simply giving them toast, was her "sanitizing" this trauma by making the bomb into a simple appliance, one in which no one dies, but ultimately coming to terms with them being gone. "Forget the past, this is your future."
#2 and #3 : The Strucker Watch and Hydrasoak are interesting, in that they kind of overlap. The Strucker Watch represents who recruited them and her idealization of him, as a powerful influential man of refinement who was going to give her everything she ever wanted, "Strucker, he'll always make time for you". Hydrasoak continues on that, but represents the twins being fed up and frustrated protesting with no progress, on the edge. Hydra let them "get away" from that and soaked them in the powers of the infinity stone, making her extremely powerful, "Unlock the goddess within." If you notice, these are very positive commercials, and much like sanitizing the bomb in the first commercial, it's her trying to cope with the fact she got her powers from very bad people and trying to tell herself she shouldn't be ashamed of that.
#4 : Lagos Paper Towels is pretty simple. When she blew up the building in Lagos, killing all those people. It's symbolic in that not only does she never make the mess (it's the kids, or the husband. Likely internalizing that it was Crossbones that did it by blowing himself up.) but she wipes up all the "blood", fixing the problem. Once again, she is trying to sanitize the whole thing, attempting to remove herself from blame and wiping the slate clean. "When you make a mess, you didn't mean to."
#5 : Yo Magic is a bit more difficult to parse, and I honestly think it has multiple meanings, but I think the main thing it represents is her time trapped on "The Raft". She was stuck in the middle of the ocean, with her powers taken away from her, and likely being studied by the government for ways to utilize her powers. The shark represents a manifestation of her desire for freedom (hunger) but her inability to do anything due to her magic being suppressed (unable to open the cup). The kid wasting away is what she thinks would happen to her if she ever lost her "magic" again, and the tag line "Yo Magic, it's for survivors." is once again her coping with that loss of power. She got out, and so she won't let "her magic" ever escape her again, because if it does, death will follow for herself and those she loves.
Now there are two events missing so far from this idea. The death of Pietro, and the death of Vision, but I think the reason no commercials for those events exist is due to just how tragic they are. The others, she is willing to remember in some way to work through the grief and frustration and lies by sanitizing these events into commercials, but the death of her brother and her lover deserve no air-time. There is no way she can "justify" or "overwrite" those memories, and thus there is never a commercial for them.
