There's a distinctive single amber pulse of the (normally blue) radio button before suspend occurs.

No amber pulse of the radio button. With and without drm-next-kmod: if boot is hybrid UEFI with CSM, then suspend occurs, but resume fails. No beep, the computer restarts. debug.acpi.resume_beep=1 in /boot/loader.conf for an audible beep. ---- Please: might graphics/drm-devel-kmod be better for either the tearing (without CSM) or for suspend?
not sure this will address this specific issue - but have you tested setting this sysctl knob and seeing if that fixes your resume issues:
