It isn't impenetrable. ChromeOS and Android are Linux based after all. If you don't want to be prayed upon by Google you can use things like UBlue (inc. Aurora, Bazzite), PopOS, or Mint.

The advantage of PopOS and UBlue being you can download an image with Nvidia drives pre installed.

PopOS is a very mac like interface so you might not like it. Otherwise it's pretty much install and go, has good community support, and even comes pre installed on some high end machines.

In the case of UBlue they include images for specific manufacturers of laptops like ASUS, Framework, and Microsoft surface. You also get fully automatic atomic upgrades with rollback in case of failure, similar to Chrome OS. This means even if you do something very stupid like reboot in the middle of an OS update, it won't matter. It's engineered to be almost unbreakable even for new Linux users thanks to being partly immutable. You get a choice as well between varieties for normal users called Aurora, one of gamers called Bazzite, a development one called Bluefin, and a server version too. Being based on Fedora it's also reasonably up to date as well, but without sacrificing stability like Arch does.

Linux Mint is the classic easy to use Linux that runs on most computers made in the last 10 years and often older. It does sometimes struggle on newer machines with drivers though as it's not using an up to date kernel. What it's good for is that it pretty much just works when you have it installed and set up. It's popular so you should get plenty of community support. It's a quite similar interface to Windows while arguably looking better and definitely using less resources.
