The baseline is not really compatible with the question imo. I can't think of any conceptually coherent setting that could be designed to fit 5e PCs rather than simply managing to continue functioning in spite of the fact that the PCs are the very embodiment of
starfish aliens with no ties to or dependency on anyone/anything in the setting.
Settings like eberron and darksun were possible because PCs had needs their players knew about and it was obviously possible to make big foundational lore choices at the setting level by tweaking how/if those needs are filled. I can't even say that wuxia/xianxia fits because those stories tend to involve characters who struggle under heaven's will & similar with real need for cultivation resources that allow them to skirt the line of power on top of actually having to depend on the world in various ways. At best author self insert isekai would
kinda work as long as the table in question agreed which single PC was the main character and accepted that everyone else was nothing but sidekick or meat computer for
The Star.
