I have designed a "daughter board" for a Pi Zero W and I am starting to layout the PCB. I was wondering what your recommendations would be for ground, 5V and 3.3V connections. I plan to put a 40 pin header on my board and plugging in the Pi Zero.

Do you recommend connecting all the 3.3V pins on the header to the 3.3V bus, all the 5V pins to the 5V bus, and all the ground pins to ground? Or, just one of each to each power connection?

Thanks!

I would connect them all as you have described.

I think it is a very good option. However, if you ever want to design a Audio input,output and power interface for Raspberry pi zero W, you can make a design like this:
