Dialectics of Nature is the right route. It's fun to learn dialectics through exploring nature. A landscape materialistically transforms solar energy into higher and lower-grade forms, biomass and waste heat. It does so through structured interdependent relationships that are constantly evolving. You can build a really intuitive sense of dialectical laws in seeing how a river shapes plants that shape pollinators that shape settlements that shape rivers, tracking the energy and how it changes between quantitative and qualitative states. Contradictions are easy to point at, and you can plainly see continuity and ruptures' impact on secondary/tertiary systems.

The big strength of dialectics is that it's holistic. Everything is dialectical and intertwined with everything else in some way you already want to read about. See it in the systems you're already interested in and it's just a super engaging way to learn about their intersectional angles.
