Can't speak for everyone, but since pretty much everyone seems to have unlimited data and the speeds aren't that bad the consumer behavior probably doesn't change at all if you're on wifi or not.

That said, 35GB average still seems rather high. I'm interested how much I'm using, but I only have usage data from the past four months and those months aren't really that representative of what I would call normal use.

According to my iPhone, I've used 7.7 GB since last December. Of course, I've been spending more time at home than usual, but even without a global pandemic, I'm mostly at home or at work, both where I have Wi-Fi and fixed Gigabit connectivity.

I'm definitely not the biggest consumer of data but at least I don't have to change my browsing behavior at all whether or not I'm on Wi-Fi or not. There's also the luxury that whenever I'm out with my laptop, I just tether instead of trying to figure out how to connect to the local Wi-Fi.
