I guess I'm more of a "mainstream" fantasy fan? So those are my go-to books when it comes to the genre. The reason why I brought up that stuff about the "price of magic" is because the whole concept of magic having a cost is sort of popular now, I think.
The Witcher uses it a lot:

Shadow & Bone does it too:

It's harder to do this in superhero comic book stories, but I understand why Marvel and DC have sort of "tried" to adopt this trope. And as I mentioned earlier, I REALLY like the fact that of the three main magic users in the MCU, Strange is the only one in it (so far) that had to learn magic without possessing any kind of powers innately. He couldn't use magic so quickly like Loki and Wanda did in their own series because he had to study and train to become a sorcerer. Plus, I sometimes (probably wrongly) think that Strange is a bit like the Green Lanterns. If his "willpower" and/or "confidence" falters, he might not be able to use magic so effectively. Like how some gifted and talented athletes totally CHOKE in big game situations no matter how much they practice because their nerves are shot. In addition to that, for ME, I think that if you can study and learn magic, I assume there must be rules. That's why I favor magical academies or whatever the hell they call them.
