I've always read as "Ar-see-us". If I recall that's what the japanese dub had used for Arceus' movie appearances.
My brain always wants to read it that way, but between the RKS System and Galar driving the point home with RKS Laboratories (Arceus Pharma in the Japanese version) in Poke Jobs, "Ar-kee-us" seems to be accepted as the correct pronunciation.
