Fighters aren't that hard once you understand them, the trick is finding one you like enough that you can stick with it to learn the fundamentals. For me that game was Persona 4 Arena which I absolutely adored. Are there any fighters that interest you aesthetically? Guilty Gear, Blazblue, Street Fighter, Soul Calibur, Tekken, Under Night In-Birth, anything? In all honesty I really enjoy the soundtracks for Blazblue,Under Night, Guilty Gear and Persona 4 Arena, which helps a lot. I can try to help ease you into the basics of a fighting game, which isn't hard at all, even though it looks intimidating it's really not.
Also, are you looking for something that's more co-operative, or more competitive? A really basic co-op game that comes off the top of my head would be Final Fantasy Crystal Chronicles Remastered Edition which you can do with others, assuming you aren't in Aus/NZ in which the game servers are fucked and Square isn't fixing them.
