A Fidelity retirement date index fund would be the easiest choice. Pick whatever date gives you the bond exposure you would like.
I prefer to have separate stock and bond funds. FZROX with FXNAX would work nicely for that.
I also like to have international exposure. I use FSGGX, which is Global Index except for the U.S., including emerging markets.
And just to be a little different I like FSMAX with FXAIX instead of FZROX. FSMAX is a total U.S. market index minus the S&P 500, while FXAIX is the S&P 500 index. That gives me a small-cap tilt.
Summing up, I'm:
FXAIX 25%
FSMAX 25%
FSGGX 25%
FXNAX 25%
All low cost Fidelity index funds, easy to buy, sell, and exchange at will. Although they don't like you selling less than 30 days after you buy.
