Reducing the font size might be the reason for icons to look too big in comparison, whereas the display was just entirely scaled up somehow… I have no idea (my Bookworm looks as above, but it's not 100% stock), but maybe try X11 instead of Wayland (if that was Wayland), just in case it's a weird misdetection of the VM's screen characteristics?
I might give this a try later if need be, I have a VM at hand (not under GNOME per se, but that could change and could be made not to matter)
