Yes, Total Return is the sum of dividends and share price appreciation. SCHD started in 2011 and has had slightly worse total return than either the S&P 500 or Total Market funds. Its worst drawdown is slightly less severe than either of those. Depending on your tax bracket, it can be less tax efficient than the broad index funds. Fund expenses are 0.06%, not much more than S&P 500 or Total Market funds.
So it's been a decent stock fund, but not outstanding. Since it is excluding high growth, low or and non dividend paying stocks, it won't be as diversified as the broadest index funds.
Some people like high dividend funds for the simplicity of not having to select something to sell when they need money, but make sure you understand that does not change the risk profile much, this a stock fund that in recessions can have deep drawdowns and reduced dividends, it is not bonds.
