Both don’t ship with their own Wayland compositor, but there are enough to choose from.
Xfce comes with a wayland session using labwc out of the box, but was also tested with Wayfire. The devs state you shouldn’t hold your breath waiting for the native window manager xfwm to be ported into a Wayland compositor, since they don’t know if/when it will be done. Almost all other Xfce components support Wayland now, while retaining X11 compatibility.
LXQt’s newest stable release has full Wayland support, with 7 different Wayland compositors to choose from within a GUI settings menu: Labwc, KWin, Wayfire, Hyprland, Sway, River and Niri

Might push to run Sway + XFCE on my laptop, opposed to i3 + XFCE
When I first started using KDE and Sway I was so used to the Xfce apps that I installed the xfce4-goodies, running on top of Wayland. So fucking good memories.
I’m currently using sway/ mate on my chromebook. Ii like the idea of not switching between Wayland & x11 when switching DE’s
