Pretty much just Googly stuff demanding Chrome or Vivaldi and Apple stuff sometimes being easiest in Safari.

I also use Safari as my “Web app failed to handle multiple accounts” browser (Basecamp & Replicon both barf in delegated Google auth if you are logged into multiple Google accounts simultaneously). Mostly by dint of it being my least-preferred browser, so sticking to just my work Google Account hurts least there.

For Google, it’s Meet that just doesn’t work anywhere but Chrome itself. (Google Docs mostly works outside Chrome, except that copy-paste has been broken in Firefox for months.)
