What would be your recommendations for someone trying to get into Wanda?
There is so much Lore™ with Wanda that they never stop bringing up that you're always going to have questions and be a little confused, no matter where I tell you to start. That said:
Scarlet Witch by James Robinson: The Complete Collection
Scarlet Witch by Steve Orlando Vol. 1: The Last Door
Scarlet Witch by Steve Orlando Vol. 2: Magnum Opus
Scarlet Witch by Steve Orlando Vol. 3: Scarlet Witch & Quicksilver
Vision & the Scarlet Witch: The Saga of Wanda and Vision
There was a time when the answer for where to start with Wanda was some very old, scattered issues of Avengers, and nowadays, I feel like the solo comics are a good place to start. The last one is a collection of comics from the 80's, but those stories are focused on her and Vision.
From there, you can try out Steve Englehart's run on Avengers. Busiek's too, I suppose. Various events, both recent and old. It's hard because sometimes, rather famously, Wanda, as a plot device, will be very important in a story, but then she's barely in the story. Like, she's comatose, she's off-screen, people are talking about her and she's not there. Which, I think, makes them weird to recommend for her, in spite of what it looks like on paper. If you want lore, you can just read a summary of the lore.
And also, those comics are not the best quality and contain many questionable writing decisions, far beyond the normal stuff you get in Marvel comics. I often have quibbles with the things I recommend, elements I have outdated and insensitive, but there's a big difference between that and Disassembled, which I would be hard-pressed to say anything positive about.
