I can't vouch for the correctness of this, but according to Google AI, there are various reasons for this, but one that you can check is that they reserve that section for groups of 3 or more. If you are searching for only 1 or 2 seats, you can try searching for a booking for a bigger group to see if those seats show as available.
Mainly for families with children who don't pick their seats but need to be seated together. Sometimes a row will be used for crew rest on long haul, but on short haul it's almost definitely for families.

Exactly this. Crew rest will never be in the last row. Delta realized a few years ago that it's better to block out the last few rows and assign those with small children there than having to reassign a large number of people, including those that paid for those particular seats, in those situations.
