SCHF or VXUS?

I am a 21 year old investor who wants to retire in my 40’s so I have been dollar cost averaging (DCA) ETFs for about 2 years now. In my portfolio i currently DCA
VOO
SCHD
JEPI
QQQ
ARKK
VNQ
VTI

I’m looking for an international ETF to invest in but I don’t know if I should choose SCHF or VXUS. What do you think and why?
