We went the route inspired by gamingonlinux.com So anywhere there is a YouTube embed we instead display a static thumbnail with 2 inline buttons underneath. 1 button to accept cookies and then load the embed and 1 button to view the video directly on YouTube in a new tab. It works nicely and also pushed us to switch most of our videos to being first party hosted instead of YouTube.
