, given your choices I'd go with:
) Spartan 500 Index Fund Advantage Class (0.07%)
) American Funds EuroPacific Growth Fund R6 Class (0.50%)
) PIMCO Total Return Fund Institutional Class (0.46%)
FUSVX is only large caps and RERGX is only developed markets, but they'll do. If you have an IRA you could use that for the missing US mid/small caps and/or foreign emerging markets.
