PCB Design review. How did I do?
I haven't had a deeper look. I think the schematic might be missing a page for the connector nets of the mPCIe.
Make sure you order the right thickness PCB. I think its 1mm thick for PCIe cards. the usual 1.6mm PCB won't fit in the connector.
You could rename the LEDs as PWR,STAT and WORD instead of red, blue and green, there is no information, the user can see the color of the led.
I'd also add a lot of test points, its very helpful in debugging. Consider adding them on power nets, and CAN Rx Tx, status signals (sometimes the LEDs could be soldered in reverse by the manufacturer), You can also connected some free GPIO to test points, this can be helpful in debugging firmware, you can flip this GPIO in some function when you need it.
Cheers!

Designing an SDR with PoE Power Supply: Synchronizing SMPS and Managing Heat and Noise
I have done routing for high speed interface like USB3.2, PCIe etc.
Routing single DDR chip should be doable, there are some challenges with routing more chips.
@ke7c2mi What CAD you are using/planning to use for this design?

How to optimize PCB design for DRV8320 and STM32G431RBT6TR to minimize vias?
since you are using 4 layer with 2 gnd core layers, you can use as many vias as you need

The pull up resistor on reset, you could place near the pin on IC

Which software could I use to draw this on my computer?
you could also try inkscape if its just a 2D drawing you are looking for.

Is it profitable and especially possible to create a somewhat intelligent cat food dispenser?
the profitability depends on a lot of things, but I remember seeing lot of products around cats on kickstarter, I think there is defiantly a market for this type of products.
