I already know that it’s spyware but in the case that I need to use it for work and school on my Linux laptop, do I need to worry about configuring something so that it won’t have access to my whole system like it does on Windows? I’m on ZorinOS/Ubuntu. Thanks in advance
Neither isolates everything. Both have some isolation features. The features enabled by default vary from package to package, so you would have to look at the packaging permissions of each one to find out.
For a bit more isolation than a flatpak/snap, I suggest creating a separate user account for running chromium (or any other moderately nosy software). Note that linux lets you log in to two accounts at the same time, each with its own desktop, and switch between them. Check out your desktop environment’s “switch user” function.
For even more isolation, you could run chromium in a hypervisor-based virtual machine.
