There may be some cookie management extensions that give you a different workflow that works better for you.
If the aim is to keep a mostly-empty cookie jar, with cookies from only a few necessary sites, then Self-Destructing Cookies works well. Cookies can be set while you visit the site (although it can also block tracking cookies), then they're wiped as soon as you leave. The end result is that logins etc work, but trackers are either blocked entirely, or non-persistent.
It integrates smoothly with the existing cookie settings, too, so if you've configured a site to have session-only cookies, or be entirely blocked, then that will still take effect. As the documentation says, SDC effectively gives you a new cookie policy: keep while associated tabs are open. Which, to my way of thinking, is how people intuitively expect login cookies to act.
