RSUs and ESPP, cash out and invest in ETFs, Dividends, SPY, or leave it?

I get a good amount of RSUs and contribute to my ESPP. The ESPP returns about 40-80% gain each time the share purchase happens since my look back price is so low. I’m thinking I should cash the RSUs and ESPP shares each time they are vested and purchased and diversify. My company stock has gone from \~$24 when I started 3.5 years ago to 70-90 now depending on the month. It’s been at that range for about a year.

Looking for advice or what you would do in my situation. It’s around 80k a year after taxes in stocks.
