I feel the opposite though I'm an n=1 and don't have any data beyond myself. My company went full WFH during the pandemic and committed to it. Ever since we've become much more meeting heavy (I also have pretty senior IC title sadly.) Why?
Along with going WFH we began hiring from other timezones in earnest. Low cost of living areas are cheaper to hire from. Previously we were really careful about hiring teams in a given timezone together, everyone on the team used to be within +- 1 hour of each other. Now lunch times, day start, and day end times weren't in sync anymore. Before standup was at 1100, now meetings started appearing at 1000, 0900, eventually 0800. After all 0800 in UTC-8 was actually 1100 in UTC-5. My 1200 lunch is overwritten all the time by folks in UTC-6 for whom it's actually 1400.
Before you'd see people run to the bathroom or express annoyance finding meeting rooms, but now going from meeting to meeting is just a click of a button. What used to be a hallway conversation or an extra 10 minutes of hanging outside a conference room to hash out a few details becomes another 30 min time slot they book on my calendar along with everyone else.
