I think the proper way to prep is not individually but communally. See if your local government has any disaster preparation programs and get involved with those. YouTube videos are mostly for driving ad revenue and selling you garbage after making you anxious and don't solve the underlying problem of fragile global supply chains and supply shocks.
The main thing currently that no one seems concerned about is the reduction of grain production from Russia and Ukraine because of the war. This is going to have a global impact and will increase food scarcity that a 3 month individual supply can not do anything about.
