Update on the Manjaro/EndeavourOS situation
So I was able to use gpartd and remove the disk partitions. That allowed them to show up for the Manjaro installer. And I was able to install and use Manjaro.
The good news: I didn't brick my chromebook.
The bad news: I still am not using EndeavourOS.
I am going to try one more time with that strategy and see if I can get Endeavour to install this way and if that still doesn't work, I am just going to sit with Manjaro until I understand the whole UEFI/Legacy boot/MBR issue some more.
