SEO isn’t something google invented, it was just a result of their actions.

Almost all Linuxes are really private. Because of your ethics and morals, I would probably switch to Debian or Arch, and use Flatpak where possible to prevent apps from spying on one another and reading files from other apps or your system.

Kicksecure, Whonix, Tails, Qubes, … exist but they’re not needed and to much of a hassle for day to day use for most people.

They already have the Framework Chromebook, which should ship with Coreboot.

If your games are on Steam, check ProtonDB.

If not, you’re probably out of luck, but check recent Search Engine results. Best to limit results to around last 6 months, otherwise you’ll probably get outdated information. Only a few bigger non-steam multiplayer shooters work, I can only think of Overwatch right now.
