How do I make Favorites my default list, even while currently logged into a current site?

This is correct – 1Password in the browser has totally separate Settings from those in the main 1Password app. The main 1Password app will always open back up to where you left it, so if you had Favorites selected in the sidebar, then quit 1Password, it'll go back to Favorites when you open it again.

In any supported browser, you can right-click (or click with two fingers, or hold ⌃ Control while clicking) the 1Password icon in the browser toolbar and click Settings. Alternatively, you can open 1Password in the browser, then click the (≡) menu > Settings, like this:

Hope that helps!
