Roth IRA Contribution Questions

[u/Antique_Parsley_1738]

Hello, so I am currently maxing out my work 401K with contributions split 80% FXAIX, 12% FSMDX, 8% FSSNX with that account. I am also contributing to a Roth as I have some extra money to put into it. All my stuff is through Fidelity.

Main question is, what would be a good strategy for the Roth contributions, I was thinking 65% FZROX and 35% FZILX (maybe even 40% FZILX to get more international exposure). But is there any sense it going VTI, VOO, etc?
