Best brokerage for casuals?

Hi everyone. I know it’s been asked a million times but I’m just a little overwhelmed. I want to start getting into stocks just as a way to make a little extra money on the side. I want to start small, $10 a week, and I don’t really want to look at it. I just want to put some money in that I won’t notice is gone and let it grow for a while. I’ve seen a lot of people recommend fidelity, but I also have a chase account and I see that they offer brokerage accounts as well. I just want something simple, safe, easy to understand. Thank you all for any help you can provide!
