If anything, it's a pseudo-theocratic absolute monarchy, which is very much the opposite of Fascism.
Le what? It's actively suppressing the major in setting equivalent of religion, its leader was duly elected and legally granted extraordinary powers, and at this point in the timeline the Empire still has a semi-functional Senate. There are literally zero words in your alternative governmental style that are accurate.
Meanwhile, it's specist to the core, elevating humans against those non-human "others" and their sympathizer to the point of having state sponsored slavery, relies on constant warfare and conflict to exist, is permanently on a total war footing to the point that their only opposition is banking on 2nd tier starships and aging star fighters being used as justification for building and using anti-planet super weapons, and the Empire has a habit walking up to a place with resources it needs, saying "this is mine now", and shooting anybody who doesn't play along. They're space Germany annexing the space Sudetenland.
There may be similarities: emphasis on strong central leadership, use of heavy-handed force to maintain order, sexy uniforms, but not everything "bad" is automatically Fascist.
Constant warfare, blaming the simultaneously overwhelming and easily beaten alien, encouraged factional infighting in command, literally called their shock troops Stormtroopers...
Next you're gonna tell me the Nazis in Indiana Jones don't represent the actual Nazis.
