In my experience admissions at US schools know quite a bit about the typical grades in high schools in other countries. I however have trouble knowing how to interpret your grades. “Had 90% overall average” would not be top 10% where we live now, not even close. However, it would have been top 1% (barely) where I went to high school.
Whether you need financial aid will make a big difference in terms of what are “safeties”. A university is only a safety if you know you can afford it.
