Instax is nice
I was into Polaroid cameras for years ('17-'20 or so). The soft focus and nostalgia hit make it hard to evaluate the photo. The toy cameras with limited-no controls and (for Polaroid at least) unpredictable film rob a sense of control and make good photos feel more like luck than a replicable set of circumstance. The inability for rapid followups means you don't get the immediate retake because this or that was lined up wrong, and you don't get the learning from accumulating those retakes.
Everyone learns different but this idea of self-restricting to point and shoots to learn with purity is a meme pushed by camtubers who don't realize how much their prior knowledge informs their point and shoot experience. It can be done, but I figure much longer. You learn a lot by having all the adjustments of a DSLR, using them and seeing how the photo reacts, going to Darktable and adjusting shit and seeing "aww fuck I needed this different." Plus it's easier to follow along in YouTube videos and tutorials when you aren't zoning out every time they mention settings.
Not to say instant isn't fun. I still love it. But my first, 10 year old DSLR was $100 - same as 40 shots of Polaroid photos. I've taken many times that. For photography, and my wallet, I wish I just bought the damn DSLR sooner.
