The S330 has an ARM processor, so definitely avoid that one (and any other Chromebook with an ARM processor). To be honest, I would buy a cheap Windows laptop and install Linux on that rather than fiddling with trying to get it to run on a Chromebook.
Or, as others have said, leave ChromeOS on the machine and run Linux in Crostini. If you have a reasonably speced machine it runs pretty well. Although again, I would avoid ARM as some Debian applications aren't available for ARM Chromebooks.
