I've had trouble locating English language resources, but if you speak German: - finanztip.de plus their social media presence are a great way to start - Stiftung Warentest/Finanztest for general financial product tests - Finanzfluss' social media presence is great, too. - Smaller scale sources like Finanzwesir, Gerd Kommer's books plus his company's blog for well researched treatises of all things finance, backed by data. - Education by workshop companies like Madame Moneypenny that teach hands on. Those are my favorite sources.
