My Sony a7 mirrorless solves basically all of the issues you have described.

The menu hierarchy isn't flat.

Physical knobs for everything, even customizable. Touch to focus (though I prefer using the ring tbh).

BT/WiFi transfer. A bit slow (2-3 sec for a 50mb raw photo) but fine for what I need. I use a USB-c SD reader for my phone and sync the entire card to an SD card in my smartphone.

Full size HDMI built in.

I don't think I would say that cameras are dead, it's just that it's a hobbyist thing now. Most of my friends would never buy a camera except a cheapy one like an Instax for fun, they're not dropping a grand on an f1.4 35mm.
