Friend is looking at inheritance of very large piece of land and looking to sell.

So I have a friend that is inheriting roughly 2M worth of land. We have talked and plan is to sell and pay off all debt. Set his daughter up a Roth and max it out every year for her. Will leave him 1.25 if I had to guess. I told him with that kind of money go to a big brokerage and invest in an easy 3 fund portfolio. He has 10-15 years before retirement and this is what’s going to set him up because honestly he doesn’t have much else. Any criticism is appreciated. I also told him set 50-100k in a HYSA for emergency/medical whatever.
