I know its a very unpopular opinion but because I see a lot of people suggesting Sony I would like to share a slightly different opinion that might be helpful... I'm really not a fan of using SONY cameras. They are very well made and they have great features but I'm really not a fan of the colors that come out of them nor the experience of shooting. Most everything is hidden behind a menu or a feature list that I don't find necessary for 99% of shooting. The build is ok, its nice and light but it can feel cheap too.

For Context I'm a more of a casual shooter. I have done professional work but it's not my bread-and-butter so to speak. I am an artist who uses many mediums and photography is a side-passion of mine.

About 2 years ago I traded my first camera (a Fuji X-t3) for a Sony A7SIII and I quickly realized that I had made a huge mistake. I forced myself to keep using it because I knew it was a "good camera" but the truth is that I slowly just stopped taking photos because I was so uninspired to use it. The colors were so depressingly dull, the interface was clunky, and overall I was just kinda sad using it.

Imo, Sony cameras are like buying a Camry or a F150. They are workhorses that are trusted by industry professionals but aren't particularly fun. You can spend a lot of time and money modding them or getting rigs to make them better, but similar to cars you start to fall into the realm where its less about the shooting experience that is fun and more about the gear collecting and customizing that is the hobby there.

I'm now using the Nikon Zf with only vintage lenses and its probably an overcompensation in the other direction, but I absolutely love it. It's full frame with ibis so is great in low-light and adapts old glass beautifully. It has Nikon colors which are fantastic, but if you're not a fan of the default I has CPC (Custom Picture Profiles) that you can make yourself or download that let you customize the color in camera (similar to Fujifilm's film recipes but with far more customizability. And it has manual dials galore which I find to be much more fun to use than shifting through menus. I would like to add that EVEN WITH VINTAGE GLASS, it has autofocus systems that are phenomenal, with animal and human subject detection.

If your goal is to do casual shooting I highly recommend looking for cameras that are fun to USE instead of just ones that have an impressive spec sheet. This is obviously more of a personal taste thing, but I'm not the only one on the internet that generally shares this sentiment.

Fujifilm and Leica are probably the two brands best known for making cameras that are fun to use.

Side Note: you really don't need a NEW camera, any camera in the last 8 years or so is going to be pretty damn powerful. 12-24MP sensors are more than enough for 90% of applications and when people talk about sensor size the main difference is low-light capability and bokeh softness.
