Can enrollment be on a first-come, first-served basis until all available spaces are taken and then use a lottery selection process to develop a waitlist?

No. A charter school must first establish an enrollment period and, if at the end of the enrollment period the total number of applicants exceeds the number of spaces available, a lottery selection should be conducted. If the number of applicants does not exceed the number of spaces available, a lottery selection is not necessary, and all applicants can be admitted to the school.
