question about nullptr

If you were creating C code today and could use a C23 compiler, would you use nullptr instead of NULL?
I am asking because I think I will keep using NULL.
I like nullptr semantics but I don't like to introduce new element (nullptr) inside the code with no guarantee that the code will not mix both.
In the past we also didn't have a guarantee we are not mixing 0 or NULL.
I think the best scenario for a team guideline would be a style warning if 0 or nullptr is used and NULL to be defined as nullptr in a C23 compiler.
