I recently converted a game, Tribal Trouble (https://github.com/bondolo/tribaltrouble) from GLFW to SDL3. It was mostly a painless refactor though I did have some issues with full screen exclusive modes and desktop full screen but was eventually able to resolve those.

I ended writing a demo for screen mode handling to test and document the fiddly bits.

The game is Java, like Minecraft, the demo is C because I wanted to keep it as simple as possible.
