The majority of cookies don't break much at all. Or at least not that I notice; I've been blocking all cookies, including first party, for a few months, using uMatrix.
Obviously you need them for logins[1]. You need them on Twitter to view the old version of the site that doesn't require js. On YouTube, to view comments. To follow some redirects on the Android developer docs site.
