Roth IRA portfolio advice

Backdoor Roth IRA maxed out and wondering if the portfolio below makes sense for long term investing (39M, planning to max out each year and keeping this 50/25/25 allocation for the next 10-15 years):

50% SCHG - Schwab U.S. Large-Cap Growth ETF

25% VBR - Vanguard Small-Cap Value Index Fund ETF

25% SCHF - Schwab International Equity ETF
