I think most everyone in the sub-$25M bracket is better served paying a broad-based index fund 0 to 4 basis points for VTSAX or similar and using fee-only planner/advisers for tax, estate, and investment advice.
Completely agree that if OP wasn't previously a skilled investor with a track record of beating the market (extremely unlikely), that they shouldn't now try to become one.
With this amount of money, they've "won the game" and have no need to beat the market. They only need to match the market over the next 50 years. That can be done very simply, reliably, and cheaply.
Having worked at a hedge fund, most "skilled" investors aren't. I would just do what you've suggested and park it in a diversified portfolio of index funds even if I had all that money. I've seen some atrocious usage of investor money at hedge funds. It mostly goes toward stoking the ego of the partners.
