There are additional options.
From the GIRM:
61....In the Dioceses of the United States of America, instead of the Psalm assigned in the Lectionary, there may be sung either the Responsorial Gradual from the Graduale Romanum, or the Responsorial Psalm or the Alleluia Psalm from the Graduale Simplex, as described in these books, or an antiphon and Psalm from another collection of Psalms and antiphons, including Psalms arranged in metrical form, providing that they have been approved by the Conference of Bishops or the Diocesan Bishop. Songs or hymns may not be used in place of the Responsorial Psalm.
Sometimes, on feasts or solemnities that occur on weekdays, I've sung the Responsorial Gradual, which is **very **different than a traditional Responsorial Psalm - our pastor seems to prefer these as they are quite short. On other occasions the music director has given me (the cantor) the choice between two versions of the same Responsorial Psalm to sing, the one in the Roman Missal or the Grail version, depending on which I prefer.
On Sundays we've done seasonal Psalms but in the past few years we've moved away from seasonal Psalms and are now chanting the Psalms from the Missal - which I much prefer, both as cantor and participant in the Mass.
