Investing Basics – Feel free to ask the most basic questions

Does anyone invest in US equity or mutual funds? I am in US and struggling to invest in US stocks due to below reasons.

1. It is hard to find companies apart from FAANG stocks and some other stocks like Costco etc? How do we find good mid and small cap companies in US? Since most of us are born in India and know most of the companies since we have consumed their product. Atleast I am facing this challenge.

2. Any mutual funds which can give 15% type of return in US

3. Is there any small case concept in US? I couldn’t find similar concept here

4. Are there any good forum like our favorite value pickr for US stocks as well?

5. Any good investors to follow for US equities?

Any pointers for US equities will be appreciated
