Investing my first 100k USD

Hey everyone I have 100k USD in cash and I’d like to invest it. I already have an emergency fund which I’ll park in SGOV. Is my strategy optimal ? I want to make sure I’m somewhat safe if a crash in the S&P happened hence I’m putting some in metals and an international ETF.
