I can suggest an alternative: Aryan.
Regards,
Caucasian =/= Aryan
Aryan is a linguistic category, not a racial one.
There are lots of “caucasian” peoples whose native tongues are not Aryan. Basques, Finns, Hungarians, Lebanese, Syrians, Chechens, Circassians, etc.
Aryan is an ethnic designation for a group of people who are effectively Latin European.
