Two great options! I went through a similar decision criteria in February, ultimately choosing Haas over Wharton, although money was a large contributing factor in my case (I was actually rejected at Sloan).
Both will likely get you where you need to go, although I envision it will be easier to venture to local start-ups from Haas for networking and interviews. Looking at both employee reports, it looks like Coursera was the only company that recruited at either school from your list last year. This tells me that it will probably be more like start-up recruiting, where you will need to take the initiative to find positions. You could also probably do an internship locally with a EdTech firm during your first year if you wanted to at Haas which could give you relevant experience to help with full-time recruiting.
With that being said, I'm sure you could do that from MIT as well (which has an unbelievable brand within tech), but you may have to do treks to SF along the way (if that is where you want to end up) to meet with firms. Boston does have some EdTech players, but they all appear rather small.
I've also anecdotally heard from a few MIT students that I talked to when I was doing initial school research in early 2019 that the MIT career center is not super helpful for non-traditional paths, but I also heard that they were working to improve that, so it may not be an issue anymore. Haas is also very student-driven, but being in the Bay Area would make it easier to do the outreaches on your own.
Finally, if you do think East-coast down the road would be an option, the MIT network is obviously way larger on the East coast. It also offers a better chance to get into MBB (every single person I met at Haas' admit weekend going to MBB was going to the SF office, so if you want to go to a different office, it will likely be more difficult from Haas). It's also strong on the West Coast as well, so it kind of offers the best of both worlds.
I would recommend reaching out to alumni or current students who went down the EdTech path from both schools. Given your specific goals, they will be more helpful than most people on here who are taking a shot in the dark. I'm sure AdCom at both schools could help put you in touch, but if not, just find people on LinkedIn and reach out to their alumni email address.
