The blood thinning effect of alcohol has been dismissed by several studies, it's a cause of many types of heart disease. The problem is people lie about intake, and the teetotlers and typically ex alcoholics.

Ethanol is a toxin, it effects mitochondrial efficiency at incredibly low levels. Huge risk factor for dementia.

Also be careful of regional studies like the large Chinese cohort because a lot of effects are due to genetics. Bad epidemiology had people convinced fish oil would would prevent heart disease because of one study in inuit that failed to consider genetics.

There is no safe amount of alcohol.

Speaking of terrible studies. The one you linked is absolutely terrible.

Have you read of the actual paper. Their conclusions are absolutely not supported by the evidence and their methodology is statistically invalid.
