I also needed a desktop on my Orange Pi Zero 2. I installed an "Armbian 25.5.1 Bookworm Minimal / IOT", then installed an XFCE desktop using some short guide I found on the Internet:
sudo apt install lightdm xfce4 xfce4-goodies xorg
After a reboot, my desktop started without any additional configurations. It's so good that now I have a new system with a desktop on my old hardware, which doesn't provide fresh OS images anymore.
