I'm not a heavy drinker so the all inclusive packages aren't worth it to me (note I also have access to free alcohol in the evenings so my value proposition is going to be quite different than for someone without that access). If you drink a fair amount and don't have to have a specific alcohol, the packages can be a value.
No not all alcohols, wines, beers are included in the various all inclusive packages, even the premium packages. You would need to check out the specific details onboard that should list what is included.
