You have many excellent funds offered in your 401k plan. You are fortunate.
The funds you highlighted are the correct funds to use for a three-fund portfolio.
Put all of the bond allocation in your 401k using the Bond Index Fund (Bloomberg Barclays U.S. Aggregate Bond Index) ER 0.08%. That will be almost identical to Vanguard Total Bond Market Index Fund.
"In a 401(k) plan with limited choices one might very well opt for an S&P 500 index fund to serve as the domestic stock component of a three-fund portfolio." Wiki article, Three-fund portfolio, "Other considerations"
In my opinion in a plan that lacks a total stock market index fund, a S&P 500 index fund (like the Large Cap Index Fund in your 401k plan) is good enough by itself for a domestic stock allocation. A S&P 500 index fund covers 81% of the U.S. stock market, investing in stocks of selected large-cap and mid-cap U.S. companies. In the 27 years since the creation of the first total stock market index fund the performance of the two types of funds has been almost identical. Morningstar, "growth of $10k" graph, VTSAX vs VFIAX
. In the first 10 years the S&P 500 fund did better, in the last 10 years the total market fund did better, and over the 27 years the total market fund gave a little more return (0.11% per year), but at the cost of a little more volatility (risk): nisiprius post, in the forum discussion "Exchanging the S&P 500 for the TSM"
. So it seems that adding a little in mid/small cap stocks trying to mimic the holdings of a total stock market fund has historically made little difference in performance.

If you want to add the Small Cap Index Fund, then an 83/17 mix of S&P 500rRuseell 2000 funds will approximate the content of a total stock market index fund. Wiki article, "Approximating total stock market"
. In my opinion it is not necessary to add the small-cap fund, it is optional if you prefer to do this.
The International Index Fund (MSCI ACWI Ex-U.S. IMI) ER 0.12% is a total international stock index fund, very similar to Vanguard Total International Stock Index Fund.
