1. Don't dox private individuals for no good reason (rules out NYT, Washington Post, and Forbes)
2. Have ethical business practices around a subscriptions, such as letting you cancel easily? (Rules out the thousands of local papers owned by USA Today)
3. Have basic fact-checking (rules out...almost everything?)
ProPublica seems like the best, especially since I consider investigative journalism extremely important. I've heard good things about Bloomberg, but it's extremely expensive. The Atlantic and The Economist have traditionally had pretty good content, and I at least haven't noticed them violating basic journalistic or business ethics.
