Linux Distro Accessibility

Which Linux distributions are most accessible? I researched the accessibility of Linux distributions before choosing Ubuntu. My sources included 8 accessible Linux distributions by Opensource.com and 5 Linux distros for visually impaired people by It's FOSS.

I opted for Ubuntu as a solid base distribution with the Gnome desktop environment. I now question this choice, because "Ubuntu Software" does not distinguish which application packages are apt, snap, or flatpak. How do other distributions compare for accessibility?
