Switching from a 11700f to AM5 was aiming for a 7700, but you discovered a 7800X3d at a good price.
8+2+1 power stages are acceptable, though not ideal. The ASRock B650M PG Riptide offers better performance and is a solid alternative.
The board is fine, the 7800X3D draws no power so any AM5 board would do OK (though I'd try to avoid the A620 boards if at all possible). I would strongly advise at least going for 32GB of RAM. No matter how you do 16GB, you will end up with significantly less performance than a similarly clocked 32GB setup. Besides, the difference in cost between that 16GB 5200 setup and a 32GB 5600/6000 setup is relatively minimal for the amount of performance gained.
