I use Firefox Temporary Containers addon (needs Multi-Account Containers) and the Containerize addon. I've got it set up so that sites not on an allowlist open in temporary containers. When the tab is closed, the container (and thus all cookies, local storage, etc) gets deleted 5 minutes later. Sites on an allowlist get opened in persistent containers. So I can always allow (at least some) cookies: if the site is on the allowlist I'll take the time to select the ones I want to allow, since they'll actually be persistent, but for every other site I can "allow all" and know they'll get deleted soon after I close the tab.
