I'd recommend starting with Firefox, and configuring Firefox's cookie settings to always block third party cookies.
Next, if you have a good password manager that can auto-fill logins, set Firefox to delete all cookies (and everything else) when you close the browser. That way, every time you open your browser you're starting from a clean slate. I promise you'll quickly get used to logging in every time, and it won't be that hard.
Next, enable Firefox's Multi-Account Containers add-on. This basically allows you to isolate sites you commonly use into their own cookie realms. Create containers for the sites you want to isolate (Google, Facebook, LinkedIn, etc.) and set those domains to always open in that domain's container. That way, when you click on a link to Facebook it will auto open a new tab in that Facebook container.
Next, install uBlock Origin. I don't think there's a need to install Privacy Badger since you're already blocking third party cookies, but others please correct me.
Next, for websites that don't work with uBlock Origin, create a dedicated container for that domain and set to always open in that container. Then, whitelist in uBlock Origin whatever tracker on that site you need to run things properly. That way, the tracker is isolated to just that domain's container.
Overall, Firefox's Multi-Account Containers are extremely powerful for isolating site cookies and trackers. I wish they would allow you to set different cookie settings per container, so you could by default clear cookies when you close Firefox and add exceptions for specific containers, but even given that deficiency, is still the most powerful browser feature that's come out since tabs.
