Well…the Angelic Doctor is St. Thomas Aquinas for Catholics…and in fact, you will always find some quotes by him on most books on angels. Though you are quite right that secular books on angels tend to have misguided or inaccurate info.
www.catholiconline.org
Is a good source for angels, doctors, martyrs and stigmatists. Also the archangels.
www.ewtn.com
Also has some info.
A few things I remember about angels -from Aquinas- is that they
know things fully and instantly about a subject -though ONLY God is all-knowing- angelic beings can know fully and instantly about a specific subject. They do not
reason from point A to point B or use
deduction or logic, like humans do. Of course, certain things are private to God alone, such as the time of the end of the world or who goes to Heaven, etc.
Also, angelic beings are
unique and each one directly created by God for they do NOT reproduce. Therefore, each is a separate species. They have the same powers of the Free Will and Intellect, as we do, for both are spiritual creatures. Though, they seem to have placed their Wills freely under God, except for the ones who rebelled and were doomed. They were not forgiven for their transgression because unlike us, they had full and perfect knowledge and were not deceived.
Also, angels seem to be both messengers and message at once. Angels seem to have been assigned as protectors or ‘patrons’ of places and of times.
There are 9 choirs of angels:
Seraphim, Cherubim, Thrones, Dominations, Virtues, Powers, Principalities, Archangels, and Angels.
I particularly like a Chaplet in honor of St. Michael:

Some people do not realize that angels are part of the Communion of Saints, along with the saints in Heaven, so it’s right to call Raphael, Michael and Gabriel by ‘Saint…’.
Enjoy your quest!
