So that’s a huge topic but your starting with a great camera and lens.
your biggest resource is YouTube then there’s books and podcasts
so for setting up your xt30 I’d take a look at Omar Gonzalez Photography his channel is full of useful information regarding Fuji cameras and how to set them up.
Then for videos to watch on street photography Gareth Danks, Nick Turpin and Roman Fox are all well worth a watch as for Podcasts the best is Fujicast so entertaining
