I thought there was some discouragement from using breaks/continues in loops (akin to using returns in the middle of code.) I think breaks/continues/returns are fine and here's a good example of the contrary problem when they're avoided.

I see no mention of avoiding break/continue in Goddard's c coding standard. Alternatively could implement multiple conditions to end the for loop, but I've heard reviewers not like that approach either.

Would it make sense to use a while loop?

I'm not aware of a coding standard that prefers one way over the other. Without a preference/standard stated, I don't think it's worth changing code. Either way there's an iterator and two exit conditions, for loop with a break seems fine to me.
