For the test optional. (TO) high, high reaches, your score in theory should be above their 50% mark from the previous couple years. You are right there for many of these.
Because your GPA is a little lower due to Freshman year, I think you should send them other pieces of great info that you have to help them see you are ready for college work and you are going to add to the schools community.
As you make some final tweaks, picture an admissions officer (AO) at a table in February with others making final decisions - you need to help them do their job in explaining why you should be in the admit pile. Some high reach schools are admitting 50% or more test optional, but for you they may need that info.
You are hedging your bets by sending some your ACT scores and holding back on a few. You will never know what made the difference…unless an AO sends a note and tells you something about your essay or something else that was the tipping point.
This list will help for a quick look at the range:

Based on this and reading the threads from this year for these schools you would send the ACT scores to Cornell, but not Harvard. Send to Duke, but not Rice.
