I mean, the joke of the 1930s was that National Socialism absolutely was a centrist position between Monarchism and Communism. They struck a chord with central Europeans by advocating a broad ethnic sovereignty that expanded the "in-group" of would-be aristocrats while still flattering the egos of chauvinists and religious bigots. Fascism takes the founding myths of the aristocracy and extends it to a subset of the proletariat as a means of mobilizing them as a large populist unit.
The end result is a militant faction far larger and more industrial than the royalist elites, but one that still has scapegoats and class enemies among the various minorities and small neighbors on the periphery. It really is a philosophy that lives at the "center" of the historical political discourse.
You just have to come at it recognizing politics (particularly in Europe) as even more narrow and reactionary than what Fascists advocated for publicly. You also have to recognize Fascism as fundamentally unstable and quick to collapse, either into a more egalitarian socialism or a more hierarchical aristocracy, once it exhausts itself of minorities and neighbors to plunder.
