If you want a Chromium based browser Brave has a uBlock-esque blocker built right into its core but it's disabled by default because "Brave Shields is enough protection" (it isn't, given the stats I see when enabled). Anyway, you can turn it on and it uses the same blocklists uBlock uses aswell.
Vivaldi would not stop offering to sign me into google automatically on sites that support it, it kept re-enabling it somehow. How this is enabled on a privacy-aware browser is beyond me. Brave is pretty good once you disable all the crypto stuff.
Wait, really? There's something other than the default "shields" thing? Where is this and how do I enable it? Been using Brave for years with all the "aggressive" boxes checked and I've never seen such an option anywhere.
