Trading with basic account

Hi, there seems no particular reason i can trade some us stocks but not others?? I have basic (free) trading account. For the capital i have to invest not worth it to upgrade.
Also some US NYSE stocks not listed atall on your platform. For example
EE Excelerate Energy, market cap 3.8 billion, it seems not listed on freetrade platform, why not?

Clearwater paper, is listed but i need standard account??
