BEST ETF’s to hold long term investments?

Hi everyone! Hope you guys are good.

I’m just starting to get into the stock market a bit, been doing some research on certain things to invest in.

I wanted to ask you guys if you had a $300-400 month budget to throw into the stock market what would be the best things to buy to hold for the next 5-10+ years?

I’m currently holding the following:

1.) QQQ
2.) VTI
3.) SCHD
4.) SPHD
5.) VYM

Thank you so much in advance
