If all of your college courses will be taken before high school graduation, it is likely that most colleges will consider you a frosh applicant, not a transfer applicant. This will generally be favorable for admissions and scholarships. Check each college’s web site to find out its definition of frosh versus transfer applicants.
Note that entering as a frosh does not necessarily preclude the transfer credit from allowing you to graduate early, but that depends on the college’s policies regarding transfer credit for college courses taken while in high school.
