Power Supply: The official CM4 IO board should indeed be powered via the barrel connector or the 3.5-inch floppy drive connector, preferably with a 12V supply. While there's no official 12V PSU, a stable and high-quality 12V adapter is recommended.
Boot Options: Yes, CM4 Lite can boot from uSD, USB, or NVMe. My mention of eMMC was a general note for non-Lite versions, but you're right—it’s rare to have an eMMC module on a Lite version’s baseboard.
Inspecting for Bent Pins & Measuring 5V:
Bent Pins: Visually inspect the CM4's edge connector and any other relevant headers to ensure no pins are misaligned or damaged.
Measuring 5V: Use a multimeter to check the voltage at the 5V rail on the GPIO header (pins 2 or 4 for 5V, and pin 6 for GND). If using the CM4 IO board, check the power input pins on the board.
