At or apogee, there is NO libration of longitude. Maximum librations are seen about one week AFTER and one week AFTER apogee, each time revealing about 8 degrees of longitude on the Moon's far side.
At perigee, the full Moon is about 14% larger in diameter and 30% brighter than a full Moon at apogee, when it's furthest away. Compared to its average distance, it's 7% larger in diameter and 15% brighter.
