For someone your age with a long time horizon, the standard guidance is a simple, cheap, and diversified index fund portfolio. I personally use VTSAX just because I didn’t know what the hell an ETF was when I started investing and I wanted one fund to cover everything in the domestic market. VOO will work about as well, although it only has exposure to the S&P 500, so you’re omitting a bunch of small and mid cap companies from your portfolio. It’ll still track very closely, though. If you buy just one fund that matches market returns and minimizes fees, and you hold it for thirty years, you’ll have essentially maximized your risk-adjusted return in the simplest way possible.

Something to keep in mind is that you can still make the 2022 Roth IRA contribution (up to $6,000) until Tax Day, even though we’re well into 2023.
