Yep, great to see another lady biker
Agree that bikes aren't gender specific - you go with what you love! Try as many as you can before you decide, and be aware that you may 'grow out' of your first big bike fairly quickly - or maybe not!
Around the 600cc mark is a great starting point, from the perspective of size, weight, handling, insurance, fuel economy - they make great bikes.
A lot will depend on what style you like, what riding you want to do, and of course what you feel comfortable on, and what your finances allow.
Be prepared to spend proper money on your kit - good quality waterproof and warm kit isn't cheap but oh, so worth it when the weather catches you out
Best of luck
