With regards to video editing, Davinci Resolve is very powerful and free....works on Windows/ MacOS / Linux. There is a paid version, but you don't really need that.

As you'd expect, there is a learning curve, but YouTube will get you started and it's not that difficult to get into it.
As for camera types, depends on what you'll be shooting. Will be it be in all weathers, will you want drone shots (might want to check Turkey's rules on drone flying), will you be shooting in the dark or low light etc. What is your budget?

If I were you, I'd download that free software and start messing around with your phone now. Learn the basics of editing and using the camera to tell a story and then decide. If you like the process and enjoy it as a hobby, then you will be more aware of your needs and make a better purchase.
Personally, I sold all of my expensive DSLR kit and lenses as smartphone camera technology hit a certain point. What I've lost in quality, I've made up for in portability and always have the camera with me. I really don't miss lugging around a large camera bag and 10kg+ of kit all the time.
Given the price point of decent dedicated cameras, I wouldn't rule out something like the iPhone 13Pro or a high end Samsung.
Also, remember most people view videos etc on their phone. So whilst the camera captures a tonne of detail and subtlety, most of it is dumped when watching on YouTube on a 6" phone screen.
