Apple - MAC or Other Larger Monitor & Printer Wanted (West Los Angeles)

Hello, I am with a non-profit and a computer was donated to us but we don't have a monitor for it or cables.
We are looking for a larger monitor if possible and it should be newer then 2012, to work well with the computer we have.
Larger like a 27" would be really nice.
It would be great if it had internal speakers and a built in camera like a Mac - Apple or thunderbolt type monitor.
We would also like to find a MAC laptop or computer that is newer then 2012 or is at least running Catalina or higher and a printer that would work with Apple - High Sierra, and or speakers for a mac and a camera so we can zoom.
Please tell us what you have and what you want for it? Thanks so much!
