I read a book a while back called Who we Are is How we Pray, and it was based on one of the popular personality type analysis styles, probably M-B, and it make OPs point. For instance do you prefer formal set devotions like rosaries, chaplets, novenas with in-built rules and formulas. When you read scripture do you approach it as study, as meditation, as instruction. Are you drawn to contemplation, silence, journalling, group prayer. What style of retreat benefits you the most: a group of people who listen to talks, then do some sharing or process activities, or a silent retreat with brief talks or scripture readings, mostly meditation. Do you prefer to pray with others or alone. How do you manage silence. do you like music, choral or instrumental, when you prya. what type of music moves you spiritually: contemporary praise and worship, chant, traditional hymns, taize, Gather-type, etc.
I do think there is more to it than personality type, there is also your own stage of progress on the spiritual journey, so your prayer style can change over time as well. Spiritual Passages by Fr. Groeschel is a good short guide to this.
