I have the same issue. My workplace uses Google to store their documents which need to be accessed on a daily basis. I use Firefox for my personal web browsing and Brave for Google or work related stuff. Isolating Google/work stuff from my personal browsing has been working for me. I also use Thunderbird if I only need to open or send an email via Google. Brave has ad and telemetry blocking options and you can (for now) still use Ublock origin.
I was using BitWarden and I’ve now fully moved to Proton Pass. No problems!
