i went straight for hormones after having my sperm frozen. pretty much all i did before that was shave my arms and legs a few times. its working out well for me. i cant tell you just how good i felt when i felt my boobs start growing and got my first taste of gender euphoria. it was like i had never been happy before and finally felt it for the first time. theres no wrong way to transition, you can do things in any order you want and dont have to do anything you dont want to, you will still be trans enough and doing it right.
that said if you are interested in hormones you should know the changes they cause take the longest of any of the other changes you might make, so you might want to start sooner rather than later. keeping up with hormones doesnt take much effort so you can enjoy your body slowly changing while working on other things.
if you're not sure what hormones to take or how they work you can peruse transfemscience. they go over a lot of the basics and provide references to supporting scientific literature for their information. i found injections to be the most conveniet and effective so went straight for those.
