Need help on home office setup

Hello folks,

I've been needing some assistance as to what piece of hardware I will require to achieve my goal setup.

I have the following:
1. Desktop PC
2. Laptop
3. Macbook

I am trying to figure out the best way I can dock both the laptop and macbook, and connected to my mouse, keyboard, and monitor. If possible, I would also love to have both be connected through a hardline internet connection.

Do you have any suggestions? Thanks!
