My take: take 10-20% of it as a learning fund, try and deploy that over the next 3 months, into some combo of #1 and #3, as a quick way to get some initial experience (though note that results won't be clear until 10 years!). Only invest what you'd be willing to lose etc. Then once you've done that you'll be in a good position to figure out what to do next.
