Although on all modern distributions, systemctl reboot is available (and OpenRC, etcetera, do provide equivalents regardless), it’s not particularly kind to the DE: especially for GUI applications, it appears to send a SIGKILL. In this context, does an equivalent to KDE Plasma’s qdbus-qt6 org.kde.Shutdown /Shutdown org.kde.Shutdown.logoutAndReboot exist, wherein it prompts the user to force-close any uncooperative applications, or cancel the shutdown?

Take a look at the gnome-session-quit command. With no options it triggers a logout, with --power-off it shuts down, and with --reboot it reboots. Under the hood, it shuts down GNOME in an orderly fashion, then triggers a systemctl reboot for you. It’s the same codepath as the GUI shutdown buttons in GNOME.
There’s also a DBus API if you want to do it programmatically, rather than on the command line. See Shutdown(), Reboot(), and Logout(). The gnome-session-quit command just talks to this DBus API for you
