Which are the sweetest alcoholic drinks?
Each person will perceive tastes a little differently and nothing is full proof in this domain.
Since you are a novice, it may be good to avoid the liquor unless you are using them in some cocktails. In this case, I would go with vodka.
For the list you site, I would give thought to Coronado Mermaid’s Red Ale.
A well balanced, medium-to full bodied beer, red in color and very flavorful. The red color and slight caramel-roasted flavor comes from generous amounts of caramel malts and a touch of chocolate malts. Well hopped to balance the malty sweetness, and dry-hopped with cascade for a full hop flavor and aroma. - Coronado Mermaid's Red Ale
Stella Artois would probably not to your liking. But again, you may enjoy it.
I find some light beer quite sweet, but that is me.
In order to help you discern what wines are possibly sweeter, I am posting a couple of wine sweetness charts for the benefit of all.
Red wines have tannin which makes wines taste less sweet than they actually are.
White wines have higher acidity which can make wines taste less sweet. - Wine Sweetness Chart
