While she certainly enjoyed this surprising boon and turn of events at the moment, when Wong confronted her about it she outright rejected it and said she only cares about being with her kids.
This a good moment though to vent how frustrating it is how many people bring in outside knowledge or catchphrases they don't even really know the meaning of and incorrectly apply it to the material at hand.
For example this entire nexus being thing that I see people bring up all the time and it drives me insane when people do since it's an entirely made up construct that is even contradicted by the source material. There are other Wandas in other universes and there are other Darkholds too. Therefore it's entirely possible that there are other universes where their respective Wanda did take up their birthright and went to rule over everything as the Scarlet Witch just like there are ones who went to have a family life.
Not to mention that it's impossible to physically travel the multiverse without the power of a single teenage anomaly. Dream walking is only a temporary type of possession that requires constant upkeep. Not to mention that all of this risks the destruction of universes through incursions which are real and we have seen how that looks like. You cannot be a ruler of the multiverse no matter what with the rules that we have been shown. A Scarlet Witch could bully her way through most opposition at whatever place she currently would be but never more than that.
