I'm guessing most of the Christians that post in RGT will say yes, including me. I think if you leave the question broad enough most Christians in general would say yes. In many cases they'll think those valuable insights are subsumed under Christian teaching though
See for example
The Declaration on the Relation of the Church to Non-Christian Religions in Vatican II.
Quote:
Thus in Hinduism, men contemplate the divine mystery and express it through an inexhaustible abundance of myths and through searching philosophical inquiry. They seek freedom from the anguish of our human condition either through ascetical practices or profound meditation or a flight to God with love and trust. Again, Buddhism, in its various forms, realizes the radical insufficiency of this changeable world; it teaches a way by which men, in a devout and confident spirit, may be able either to acquire the state of perfect liberation, or attain, by their own efforts or through higher help, supreme illumination. Likewise, other religions found everywhere try to counter the restlessness of the human heart, each in its own manner, by proposing "ways," comprising teachings, rules of life, and sacred rites. The Catholic Church rejects nothing that is true and holy in these religions.
I can't find a great reference but I know eastern orthodoxy tends to take a similar view to Vatican II. I've heard protestants say similar things as well
Some valuable insights:
In Buddhism, the concept of
pratītyasamutpāda and its exposition in Buddhist teaching on
suffering and the Noble Truths.
In Hinduism, the relation between Brahman and an
Iṣṭa-devatā, that is the Divine beyond all forms and names, and the Divine recognized in a particular cherished form. Also understood as Nirguna and Saguna Brahman.
I feel like in Hinduism and Buddhism some of the valuable insight might not be theoretical as much as in the attitude towards life. Sannyasa and sunyata, the middle way, that sort of thing as practice more than theory. The experience of the immanence of the Divine in Hinduism and not just the rational ideal of a Supreme Being. The value of initiation and a teacher in Hinduism and Sufism.
Probably lots of other stuff but I'm rambling
