New to work from home

Hello all!
I just yesterday accepted a position as a WFH dispatcher. I’m looking for all recommendations on things for a home office, as I am setting up my first WFH space.
I have never worked from home before. Before this, I was actually working transportation for the small town school next to me.
I am located in small town Iowa, USA for reference. So everything I get is normally from Amazon unless I thrift it while in the city.
Let me know anything that made your WFH life easier. I have time to get stuff too, since I have four weeks of training in office starting the 20th.
I appreciate any ideas and/or feedback for starting WFH. Thanks in advance!
