Should I apply early action to BC and Northeastern?

I’ve been on the fence about applying early since the summer. Everyone is telling me to apply early but I want to apply to whichever way that gives me the maximum chances of admission but I’m afraid that applying early action might hurt my chances specifically. The first reason is because they’re my reach schools I got an 1810 on the SATs out of 2400 and I’m still waiting to take it again but it’s on nov 7, after the deadline (nov 1). Also I have a weighted gpa of 3.9 . I’ve taken mostly all honors and 3 AP classes. This fall semester I have all As except a B in AP Chemistry

Extracurriculars:
District secretary of district student council, representative of school student council and class student council, treasurer of NHS, member of key club, homework club, and health occupations club, LGH Volunteer, summer job, week day camp volunteer. I’ve also done winter track for 4 yrs

Another reason I’m on the fence is because I’m not completely in love with my common app essay and I still haven’t written the supplemental essay for bc or done my resume for northeastern. The next reason I’m on the fence is that I notified my teachers that their writing my recommendations but didn’t tell them I was applying early action so I don’t think they wrote it yet but I want them to take their time. There is only a week left until the deadline.
What do you think I should do? I’m so indecisive. Everyone is telling me I should apply early but is it worth it to rush myself to get these things done? Especially because their my top schools I want to greaten my chances against more competitive applicants. Is there a chance I might get deferred to regular decision if I apply early? I also heard that BC and Northeastern really appreciate early action.

Also do you think I have a chance of getting into these schools?

Your chances at Cornell/Brown are very low with an 1810 SAT - they reject students with far higher scores. I’d apply EA to Northeastern if your teachers can get their recommendations written on time and you can polish off your common app essay, because Northeastern doesn’t have any supplemental essays. In all likelihood, you’ll be deferred to RD if you don’t get in, and there’s always the chance of an improvement in your SAT - if your scores improve in November, Northeastern accepts any test scores sent before Dec. 1st.
