So finally switched from Windows to Chrome OS for my private use and I really love how the device performs.
I do still own Windows laptop but I use it only at work.
For ChromeOS, a great security configuration! ChromeOS is mostly secure as-is, but you added a lot of extensions to make ChromeOS as secure as it can be I have a ChromeOS device and set it up similarly to you. For mine, I also use Ghostery as my tracker blocker.
