Creating WFH station

I have been WFH 5 years working on my MacBook Pro at the kitchen table, but recently my son knocked over a glass of water and I had to get most of the computer replaced (it was not totaled).

Now that I am getting it back, I want a WFH station. No guarantees that my son won’t knock another glass of water on my desk so my Macbook needs to be protected.

I have an L shaped desk with a station under the desk for an old school PC. I can dock the MacBook there with a child lock.

What I am looking for is:

1. External monitor (not curved)
2. Keyboard - must be quiet
3. Mouse
4. Station to place Macbook in
5. Webcam (maybe)
6. Speaker
7. Connectors

Cordless preferred for mouse and keyboard. The computer has 4 thunderbolt/USB-C, HDMI, and 3.5mm headphone jack, SDXC card slot, MagSafe3 port.
