I've been in your shoes, making things that wide is a curse. true power comes from splitting it into 2 or 3 sections horizontally, otherwise every thing is just on one line and is hard to read (that's why most websites have a max width)
my go to is to use a tiling tool like powertoys on windows or KDE's built in tiling zones on Linux for putting windows next to each other in a nice and usable arrangement
