Help With Stir Fry

I've been eating more stir fry recently and would like to know what are some common recipes for stir fry. For context, I have little to no actual experience cooking besides very basic recipes. Here is what I normally use now:

Beef top round steak

Rice Vermicelli

Teriyaki Sause

Carrots

Zucchini

I am wondering the following questions:

1. What beef/steak would be best to substitute? (Cheaper option preferred)
2. Instead of Zucchini what green would work? (I'm currently thinking about cabbage).
3. Is there anything I should add to round this recipe out?

Thanks
