Should I apply for fall 2022 or spring 2023 or fall 2022

Currently, I am studying Bsc. Life Science (3 year degree) from Ramajs College, University of Delhi. It includes main core subjects; zoology, chemistry and botany and out of all these, I am most interested in Zoology. Given below are my academic credentials: 10 th- 89.3 % (PCB) 12 th-88.8% Graduation - 82.5 % (till 4 th semester) Basically, I want to pursue Masters from top university from abroad, want a job/ research and eventually want to settle down abroad only. I am confused between masters in "biomedical science" V/s "masters in immunology" v/s "masters in pathology" v/s "masters in public health". At present, I have not made any CV or SOP, but I will definitely start doing it in near future. What do you suggest which country should I target in order to fulfill my above stated goals in best possible manner along with high scholarships/funding facilities. Also, which intake should I plan for, fall 2022, spring 2023 or fall 2023, since cv, sops, ielts etc. will definitely take some good amount of time. Looking for honest and helpful #Masters
