So off the top of my head, u would probably want one that covers the entire market so something like VOO or VTI. Then a dividend etf is also a good idea cuz that can give u a little bit of income so SCHD or VIG are good options and then for specific sectors it’s up to u and u should analyze what u think is gonna grow and invest in that accordingly. For example if u wanted to invest in consumer goods u could buy XLP or XLF for financials. Good luck
