I hear you. I like taking photos. I like seeing my photos. I hate post-processing and organizing. It sounds like you're like me in that you wanted to go from taking the photo to "finished product" with as little in between as possible.
A rangefinder (start with a Bessa, not a Leica, if you want a RF) and slide film did wonders. I take the photos and I'm deliberate about it. I mail it off to a lab and a few days later I get back mounted slides. I can toss the bad ones, throw the good ones into a projector and I'm enjoying my photos. Beautiful, wall-size photos glowing in my face.
I love Provia, others consider it too cold, especially in shadows. A cheap filter compensates or try other film. Velvia is a bit more special purpose but when used right, it's just wonderful.
Many people think that post-processing photos only became a thing with digital photography. That's certainly not the case. If you were in a dark room, you were editing your photos by burning and dodging (ever wonder why Adobe picked those icons in Photoshop?). Here are some examples: https://fstoppers.com/post-production/how-photos-were-edited...
At a simpler level, if you want to avoid all of the middle work, there's Fuji Instax. You lose control over DoF, exposure, etc. But you go from taking a photo to having it in your hands in seconds. I got one because I wanted printed snapshots, but couldn't even bring myself to just quickly print a photo, I'd spend too much time messing around.
Want more control? Large format camera with Fuji instant film (that's something that won't be around much longer, but there's the New55 kickstarter). Get a camera with movements and you'll have more control over your photography than you ever could have with an SLR.
