A complete change of clothes. Toothpaste and brush.
Hand sanitizer
Brush, comb and ponytail ties.
Any medicine that was needed.
If you were moving to another country, and could only bring a carry on bag, what would you pack?
Meds, a couple of changes of clothes, and my dogs' food. While most other things I can buy anywhere, my dogs are on a holistic diet and I would want enough food so that I had time to find something similar and could change over without upsetting their systems. And I amnot moving anywhere without my dogs.
My meds, some clothes and a few things in my safe.
A change of clothes, my meds, hairbrush, toothbrush, and a couple of books.

I've traveled abroad many times, and I can get by in most places with just my passport, my plastic and my smartphone.
But since you're providing a whole bag, ---which really isn't MOVING in the typical sense, more like fleeing--- I would pack my Mac 💻, my earbuds, a 2nd good pair of shoes, glasses and clothes.
*Plus a wad of local currency, if I were fleeing.
