Not just Marxist philosophy I want to read and understand other schools of thought too
Unfortunately, most offered sources are implicitly biased towards Western/traditional intellectual philosophy as we live in a culture that has normalized and centered Western (male) philosophers
Oddly enough I think Action Comics’s Action Philosophers is a really breezy introduction to an international body of philosophers that you can use to further your education. Still Western biased, but less so
I.e. Lao Tzu, Confucius, Simone du Beauvoir, Frantz Fanon, et al
My personal favorite intro is Georges Politzer’s Elementary Principles of Philosophy. Politzer goes over the history of philosophy and how different schools of thought changed alongside modes of production, until Dialectical and Historical Materialism.
