Arch-based distros usually do not boot your computer into a standalone demo or live session mode. Arch Linux family members are not likely to have a user-friendly GUI-based installer to reduce the pain of manually partitioning and setting up installation commands.
EndeavourOS provides both, sort of. Installing Arch Linux systems is usually a daunting process for new users. You will not find a powerful automated installation tool with a fully functional graphical user interface (GUI). After all, this is still Arch world.
