How to figure out your play style?

Hello I am new to fighting games but think I really want to pursue getting as good as possible in Injustice 2 and maybe even getting my ass kicked in a tournament or two at some point.

But I have a problem.

Idk what my play style really is. I bought Injustice 1 and am using Deathstroke a lot. Which I'm not sure if zoning a lot is considered cheap??? But in Injustice 2 I'm not sure if I should go for a fast quick fighter or a slow heavy hitting fighter or a zoner or what?

What are the different character types? How do I figure out my kind that I like? Or do I just try all the characters and see what clicks? Also do you guys click each directional input or do you drag? Like say it is a Down Right input do you click down then right? Or do you drag your thumb across down then right? Or do you use a stick?

Sorry for the long post with a lot of questions. Just trying to learn. I think fighting games could be very fun and that I could be pretty good with practice but I just need to know how to figure out things. Anyways thanks.
