I think it’s part of your record and you can explain it. Are they looking - I’m not an AO. You could have had a perfect first year and still not get into Vandy or Rice - they are reaches for everyone.
Your ED1 sould be to where you really want to go. This is not a game. You have life and financial consequences tied to it. Emory would be better, especially if you included Oxford but perhaps WUSTL is the one with a large ED bump.
You should find the right college for you, not just who lets you in. You still have a great shot with the UCs.
Unless you have a true #1, you shouldn’t ED.
You didn’t list a major - that will impact things as well.
Dont’ forget, we are all amateurs. You asked an opinion. It doesn’t mean it’s right.
Vandy admitted 6.7% - so you could cure cancer and still be a reach. Your SAT will help because 56% applied with a test score (44% TO) but only 39% of admits were TO.
Good luck. And find the right school - don’t ED just to get in a top school, especially if it’s not he right school
