Well, you said your macbook died, not your disk, that means, you could get it out and depending on whatever model you have and year, it might be easy to find a nice enclosure and plug it to another computer.
The problem is Passwords, Storages like Cookies, and some settings like sync chain and all that, are encrypted to your device, so even if you get the data, that will be lost forever. But you could always try to boot in another computer with the disk and get the data that way.
That’s why saving the sync chain code is important, I mean, saving it in an encrypted txt in onedrive or google drive is better than losing it all.
But If you can extract the disk, boot it in another computer (mac, which might not be an easy thing, like it is on Windows or Linux, I don’t know) then you can recover the passwords and all, if not at least you can recover most data, history, bookmarks, and the non-encrypted plaintext in a database information.
But it is a mac, I don’t know about it, I don’t know how it works, if they have soldered anything or what disk it might have, but if it was Windows I would say, it is possible you can recover everything, since it is MacOS, I don’t know. But having access to the disk would let you clone it and all that.
