Even back when wood was pressure treated with arsenic, it wasn't dangerous unless you were going to be eating the wood.
The concentration is not that great, fruit/vegetable plants do no store arsenic in the edible products, leafy vegetables do no store arsenic in their leaves at levels to be concerning, and root vegetables store it in the skin which is peeled off or not eaten anyway.
None of this matters with modern pressure treated wood that does no use arsenic.

One question, the hole in the middle is closed off on the bottom. Online instructions say you are supposed to put a stake thru it into the ground to stabilize, am I supposed to just break thru the closed off bottom or what?

It's very thin, you should be able to push through it with a metal object. I've used these several times and a piece of Rebar through that hole and driven into the ground holds them in place pretty well

Is the concern longevity? I haven't looked into how long it takes to rust away rebar, but I think it will outlast the wood
Depends on the wood, but pressure-treated pine rated for ground contact should last around 40 years. I just keep seeing garden projects that call for rebar, and it seems risky. But perhaps it's not as big a deal for something as typically short-lived as raised beds, as opposed to my most recent example: a gravel foundation for a shed.
