The other endings are definitely worth going through! Thematically, I think the secret ending is actually the most possible to be canon (i.e., going out for all time in a blaze of glory), but in terms of character development, I agree, The Star ending with Judy and Panam is the most cohesive.
At least until we get Phantom Liberty. From the trailers, it definitely looks like there's gonna be a continuation or development in V's story. And I don't want to read too much into it, but if you remember the base game's launch, almost all the cinematics/graphic banners featured a male V. But he was switched out for female V in the marketing of the game sometime during CP2077's great fiasco. It's been all female V, even up to now.
