I still use gmail and drive for work but otherwise I'm never logged into anything google at home. Today when I tried to expand on a restaurant's hours it wouldn't let me see them without logging in, although it still worked in incognito. This restaurant screenshot is just a random other example I tried, but for the one I was actually checking google had the correct hours while the official website hasn't been updated in awhile and had the old ones (website said they're still open for dinner but they've only been doing lunch for a year or so now)
I also have everything forwarding to another account, with a rule to tag the ones sent to my gmail so that they're highlighted. It's a big task at first but just do a couple every now and then and eventually it'll be done.
