How to play against modern defense as white?

So, I have no clue how to play against modern defense as white, so any tips?

Lots of freedom to pick & choose so try stuff and see what you like. I've played several things:

1 Austrian, usually transposes to Piec

2. Experimenting in blitz with this: 1. e4 g6 2. d4 Bg7 3. Nc3 d6 4. Be3 c6 5. h4   The idea is h4 before Qd2. Then almost always black plays  5. ... Nf6 6. h5 Nxh5 7. Rxh5 gxh5 8. Qxh5  and it's game on!

3. The setup with e4, d4, c3 , f4 , Nf6 Bd3   This is seldom seen these days at my level so can be challenging to meet. White must decide: early e5 or hold the tension in the center.

I'd guess most play the '150 attack' or the one with f3 [I think this is called the Argentine attak]
