How many degrees does the sidereal month orbit?
The Moon does move 3.1&deg; in the 0.23 day difference between those month lengths, but it goes 360&deg; in a sidereal month and 363.1&deg; in an anomalistic month.

The anomalistic month, from perigee to perigee, is slightly longer because the perigee moves.
The lunar apsides take 8.85 years to go all the way around the circle.

Similiarly, the draconic month is slightly shorter because the nodes move the other way in a cycle of 18.6 years.
