But everything else fed by the battery works just fine, even the next
day when the starter doesn't respond at all.

The starter is the heaviest, single draw that you have on the battery. It
would not be unusual for it not to be able to draw enough power, perhaps a
combination of sub optimal battery charge level, sub-optimal cabling and/or
connections, and still be able to run other electrical components.

The fact that the starter works OK on the bench after malfunctioning in the
a/c points to a another issue.

For example, a bad starter solenoid may work intermittently. A bad
ignition switch may fail to make the contact to close the solenoid.

If the problem is either of the above, you should hear nothing (no starter
solenoid click) and there should be zero voltage at the starter wires
during the instances when it malfunctions.
