In an ecclesial "What's Hot/What's Not" list, you'd find "Charisms" in the first column and "The Seven Gifts of the Holy Spirit" in the second. Evidently, humans can only maintain the heat of a fixed number of things, so as attention on charisms has increased, the Seven Gifts have consequently taken it in the neck.
Whether or not anything in the above paragraph is true, here is what you find in the Catechism's index under "Holy Spirit, gifts of the Holy Spirit":
charism of healing, 1508 charisms, 799, 951 charity as the fruit of the Holy Spirit and of the fullness of the Law, 1824 chastity, 2345 in Confirmation, 1289, 1303 in episcopal consecration, 1556, 1558 fear of God, 2217 fruits of the Holy Spirit, 736, 1832 grace, 2003 grace of repentance and conversion, 1433 love, 733, 735, 2712 in the power of forgiving sins, 976 in the sacrament of
Anointing of the Sick, 1520 Holy Orders, 1538, 1585-89 Matrimony, 1624 seven gifts of the Holy Spirit, 1831, 1845 what is necessary for receiving, 1310 wisdom, faith, and discernment, 2690
If you check the links (go ahead; this post should still be here when you get back), you'll find that most of these refer to graces generally, or to specific graces other than the Canonical Seven, or to the Holy Spirit Himself, Whose proper name is Gift. About all the Catechism tells us about the seven gifts as listed in Isaiah 11:2-3 is this:
1830. The moral life of Christians is sustained by the gifts of the Holy Spirit. These are permanent dispositions which make man docile in following the promptings of the Holy Spirit.
1831. The seven gifts of the Holy Spirit are wisdom, understanding, counsel, fortitude, knowledge, piety, and fear of the Lord. They belong in their fullness to Christ, Son of David.[Cf. Isa 11:1-2.] They complete and perfect the virtues of those who receive them. They make the faithful docile in readily obeying divine inspirations.
Let your good spirit lead me on a level path. [Ps. 143:10] For all who are led by the Spirit of God are sons of God . . . If children, then heirs, heirs of God and fellow heirs with Christ. [Rom 8:14,17]
If, then, there's much worth understanding about the Seven Gifts of the Holy Spirit beyond the above, we'll need to look elsewhere.
But given the profusion of terms that all mean nearly the same thing -- gift, grace, charism ("after the Greek term used by St. Paul and meaning 'favor,' 'gratuitous gift,' 'benefit'") -- we'd want as a guide someone capable of making sound distinctions and clear definitions. At the same time, these being things of God, our guide should be someone close to God, learned by Divine light and not merely human reason.
