After proper room treatment, the length and power of these modes in the room may change, which will dictate my listening position. Did I understand correctly?

Or almost. Its way less of the first and the peak of the second.

You can hear 40hz on a pair of headphones right?

Theoretically your first length mode is 42.8hz. Can you hear it from 50cm clearly if room treatment is successful? Yes.
If you set up your speakers and your listening position in the center position of your room you are still going to hear 40hz -3db less, after "theoretically" perfect treatment.

I've attached the room simulator with setting up in the middle of the room and speakers 50cm away and theoretically "perfect treatment".
In this situation 42.9hz is -3db from 85.77hz which would usually be a big peak.

Now remember its theoretically perfect treatment which in most cases is almost impossible.
