1) LAMB is not a good enough school to place so high on your list. It shows very well to preschool parents, but upper elementary parents tend to be really dissatisfied with the academics and the administration. Be sure you do your research and don't let your interest in Montessori in the abstract distract you from the real-life quality problems. If I were you I would put it below DCB at least.
2) Understand that if you match with Bruce-Monroe as an IB student, you can lose that status by moving out of the boundary.
3) Global Citizens is a new-ish school, so if you have to cut something, that's what I'd cut. It seems like you've listed other neighborhoods that are centrally located and have a lot of amenties, and then you've got Deanwood. Deanwood has certain things going for it (more affordable, nice indoor pool, Aquatic Gardens, easy to get into and out of town), but it's also kind of isolated and not as convenient as the other places you listed. I know people who love living there, but what does it mean for your commute?
4) If you put Mundo Calle Ocho and Stokes Brookland, you can live in the Brookland area, which isn't very heavily Latinx but you'd have a lot of classmates in the area, and it's a nice place to live.
