Is there any flag to tsc which makes it a bit more verbose about what it's doing? I found --terse and --verbose references, but not sure these are old flags or proposed ones, because none of them works.
I'd like to see which files it's processing, for example.

There is no flag for that.
You can find the user facing (developers trying to compile TS to JS) options with tsc --help
These and a bit more options are documented on the TypeScript website : https://www.typescriptlang.org/docs/handbook/compiler-options.html
And all options in the this file in the TypeScript source code.
Use npx tsc --build --verbose per the TypeScript documentation:
$ npx tsc --build --verbose
