Wireless Philosophy
The best first stop if philosophy is new to you. Wireless Philosophy, or Wi-Phi, has university philosophers write the scripts and record the audio, then turns them into short animated explainers, so you hear the argument from someone who teaches it for a living without sitting through an hour-long lecture.
What makes it useful here is that it teaches the method rather than a set of conclusions: series on cognitive biases and critical thinking sit beside ones on utilitarianism, the problem of evil and the sizes of infinity. It is free, and nobody is selling you a worldview at the end.
