You'll do just fine with large format! It's really great for people who enjoy mastering a (somewhat) complex process, who are detail oriented, and who seek the best quality possible and are willing to put in time and effort to get it.
Never mind my 35mm suggestions. You'd probably be bored too soon anyway, again. Now medium format, you might like that fine, because even though I like working deliberately I often like to take a camera along when I'm doing something else, and I can carry my little TLR in a small bag with extra film, meter, and some accessories and hardly notice it, shoot almost as quickly as 35mm and get quality closer to (but not there) 4x5 than to 35mm. But you can decide about that later - welcome to a new experience with a lot to learn. I think you'll have a blast.
