It sounds like your going to be very busy so maybe you wont be so focused on food. A part of my success is attributed to meal prepping- I meal prep every single week. Sometimes I meal prep meals for grab or go or I will meal prep items for those tempting nights at home where I want to eat cereal or something that is not so great instead of cooking. you will get quicker at meal prep too, I used to take 2+ hours now I can whip up my meal prep in 1hour. I also learned to not complicate it. Easy meals can be just as delicious!
I bulk prep chicken breast, and ground beef, hard boiled eggs, wash and cut up veggies/fruits, make sure to have Greek yogurt and cottage cheese on hand, It does make life easier when your prepared!
Also having better choice snacks stocked up in the fridge/pantry helps too!
Cheese sticks, jerky, flavor packets for water (if you like that) protein shakes, protein powder, protein bars (recommend Built bar or fulfil bar), unsweetened almond milk. skinny syrups for coffee...theres more its just off the top of my head these things lol
