It won’t matter. If you’re not a clear (easy decision) admit or deny, you’ll just get deferred to the RD round. If you think your essays, etc., are ready to go, it won’t hurt to apply EA.
You do have a significant advantage as a Virginia resident vs. OOS applicants. You are competing for a different (larger) pool of seats - 1/3 OOS, 2/3 Va. residents - against a much smaller number of applicants (~9,000).

Take an ACT practice test. If you score in a higher percentile, you might make that your test to concentrate on. The two tests play to different strengths.
