I was so sad when I lost xmonad support on Ubuntu 24.
I think the closest thing that could get most of the way there is https://github.com/domferr/tilingshell/

The packages I install are: xmonad libghc-xmonad-extras-dev gnome-flashback gnome-panel
(plus suckless-tools and xmobar)
That should give you a login option for "GNOME Flashback (Xmonad)"
I recall there were a couple of hacks necessary to show the Gnome Panel:
gsettings set org.gnome.gnome-flashback root-background true
gsettings set org.gnome.gnome-flashback desktop false
and then the panels you can hide or remove per your preference
