Do you have a special desk? I use a standing desk from IKEA.
What monitors do you have? Just some random 27inch screen. Nothing special.
Keyboard? I used Microsoft's Ergonomic keyboard for a long time. However, I recently wanted to get some lightweight keyboard for traveling and bought Apple's tenkeyless Magic Keyboard, which works great. It also seems to be pretty much the only regular keyboard that doesn't make my forearms burst into fire since I was grown so used to ergonomic keyboards. Maybe it is due to its low profile. I don't know. Nowadays, I pretty much use the Magic keyboard solely.
Mouse? Logitech MX Master 3. I have been looking for some vertical mouses.
Do you work from a laptop? Yes.
Do you move around the house? Occasionally.
What other equipment? Noise-cancelling headphones.
