usually when planning one’s education and career path one first discerns vocation–state in life, married v single, lay vs vowed or ordained religious,
then one discerns one’s work in life–good career counselling in school can help, most colleges offer this
then one finds out what educational qualifications are needed, or other credentials, and pursue them
it is somewhat wasteful to spend time and money to get a specific degree, then ask Hey what can I do with it? so you are quite right to think about this now
first of all, a liberal arts education is or should be the best all around foundation for any career–that would include a major in philosophy or theology as well as any other area like history or literature
usually it is graduate school that more specific study is pursued toward a narrower path of interest, and that credentials for various professions are obtained
“religious” jobs for laity include any and all secular jobs, performed for a diocese or religious institution–accounting, teaching, nursing, risk management, IT, administration and so forth.
they also include specific ministries within the church, diocese, parish, institution–writing, apologetics, teaching religion to children or adults, canon law, applied theology, scripture exegesis, any type of administrative work that requires knowledge of the faith, practice and law of the church.
the best place to go for that kind of guidance would be the theology department of the school you are considering, they should know how their grads are placed, and how they use their degrees
good luck we need more like you. even if you eventually find yourself pursuing a career in the marketplace we are all called to lifelong learning in the faith.
for instance, if you pursue the idea of graphic design, you may work for a Catholic publisher of text or trade books, or online versions of the same, instructional materials and so forth, and to do that properly you would need the theological and doctrinal background to get it right.
