Its benefit is tied in the fact that it's ever-changing. The goal of the courtship process is for the female to pick and choose which males she wants and that requires the males to both showcase physical attractiveness, capacity to provide ($$$), social status and power because women want to have higher social status by association with a powerful/influential male or at the very least not lose social status (extremely important for foids) from associating with a lowly omega male.
Back to the ever-changing part, if the courtship process is very complicated and filled with social pitfalls it makes sure that the only men who get through are good at navigating/exploiting social systems and know which rules to break and when (if you don't break any you're a pussy beta and she doesn't want that), and if you have those traits then you also probably have a high social status which, again, they're obsessed with. The intentional vagueness around what's okay or not in the courtship ritual also serves a double purpose of giving all females plausible deniability to say "Oh i didn't know you were trying to date me!!! I wasn't leading you on for resources i was just being nice!!!!" if they decide that a male they were considering isn't quite good enough to pass her tests without getting the male in question mad at her because she rejected him.
Tldr: The complexity is a test and if you're an autist you'll probably fail unless you're hot enough then it doesn't matter and she'll fuck you anyways.
