Organizing your photos is a very important aspect. Were I getting started now, I would be inclined to use Lightroom, for that reason. Which ever way you end up, you want to give the organizing problem good thought. I think processing is something you just grow into. You should do a lot of reading and youtubing to get the lay of the land so to speak. You already have very good advice here. I like the suggestions of free, and get your feet wet using something. You don't have to rush to a decision. There is an almost religious distain among some folks for using PP at all, but for most of us it is an integral part of the photographic process. As you settle in, you will identify things you are particularly interested in doing with your photos beyond the basics, and could find yourself adding an additional program from time to time for the way it handles a specific task. I use photoshop. Its what I got started with. I doubt that I would have had I not had a friend usher me into it. Its a program deep and vast. It can be confusing for sure. Im pretty sure you wouldn't call it intuitive, but once you get the hang of doing things with it, you wouldn't be willing to part with it. Thats my two cents worth.
