could be either a reference or a coincidence. that thing about squall necklace is definetly a reference. you cant accidently give denzel that necklace in the character design. and its true that he looks similar to squall. i think he is supposed to be a bit of a tribute to squall. the cetra and centra thing is probly a reference but a lot of things in the starting thread are likely to be coincidence. saying that cloud is related to squall and tidus is crazy though. they are similar and hair isnt a way to relate people to each other. a lot of this is just bpeople overthinking. square does a lot of things like these so its sometimes hard to determine whether these coincidences are deliberate or not.
