2010 Corolla won't start

Anyone know what this sound/behavior is all about?

Check your battery.

It is still too early for a bad starter solenoid but that would be your next step.

Good luck,

Solenoid is good. Discharged or bad battery, or battery connections are bad. If the battery checks out good, you may have a drain on the battery which discharges is or a bad alternator. Running a battery this far discharged may have damaged it to the point where it won't fully charge.
