From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

That's not technically true as enabling bitlocker on windows and filevault on Mac don't require two different passwords.
Mac will ask you to “log in” very early in the boot process to decrypt the disk, I assume it keeps the drive key encrypted with your password somewhere.
That's just not true I have two macs with it enabled on both and it requires a single "normal" password
That's likely because your Macs are using the TPM. Does your Linux machine have a TPM, and are you using it?
I don't think so, they are both intel macs over 10 years old and Macs didn't start adding TPM until 2017. On Mac, when you check the box to encrypt the drive during install you're prompted for an encryption password which you never need to use again unless you remove the drive and put it into another mac (or in my case add a second hard drive and use the original as "extra" storage).
