I bought a Fujifilm X-T4 for my first "big boy" camera last year and the deciding factor in my head was that the best camera is one you want to carry. The 18-55mm kit lens is one of the best + the X-T4 has easy knobs and settings for great snaps out of the box.

I shoot everything JPEG, usually 16:9, immediately download to phone, and basically delete the raw as soon as the edits are done in Snapseed or VN. Photography in the age of social media is highly ephemeral. It's there for a day and then people are onto the next story or snap dopamine hit. I prefer a form of photography that is more like blitz chess, which is to see how quickly you can snap something good and create/post a decent edit.
