Can't you only have one profile open at a time, and each one is linked to a different Google account?
Firefox allows you to have each tab open in a different container, and they don't have to be tied to anything in particular.
I can have different tabs open to the AWS console for each AWS account I use. I can also switch tabs to change between different user accounts to test interactions between users on the site I'm developing.
No. Each profile opens in a new Chrome window. You can have as many open as you'd like.

No. Local profiles have always been a thing.
Chrome's implementation has better UX for privacy IMHO; it's harder to accidentally open a tab in a different profile than expected, which I do _all the time_ in Firefox. In Chrome, Cmd+T opens a new tab in the active profile. In Firefox, Cmd+T opens a new tab in the default profile.
Yeah, the implementation could use some work. I also use the temporary containers plugin so by default tabs open in new containers. I think this gives better security than either of these defaults. If I need a site to open up in a particular container, I can always set that too.
