There are positions in chess that have been disputed for decades or more which are just now coming alive because of the ability of engines to analyse lines. The thing that's interesting about high-level chess is how players play out particular strategic themes that result from known positions (eg initiative vs material, the open H file for white in the London system vs not being able to castle kingside, play in the center versus counterplay on the flanks etc etc etc). My recommendation would be watch a really good game analysis like Agadmator's youtube channel. One like this might be fun to start https://youtu.be/vztVylqnBSo https://youtu.be/vztVylqnBSo or one of the Capablanca vs Lasker games. Alternatively John Bartholomew and Eric Rosen have fun channels where they play and commentate on their thought process.
