I tried that, but most apps just don't scale down well. Important UI elements just disappear, while less important elements maintain their size, unless the app has most of the screen. Those are apps like teams and outlook that I would expect most office users to keep open all the time on Windows (teams is really bad about assuming I want to see the avatar of whoever is speaking more than their slides). Edge did a little better, depending on the page I was looking at.
This is one of my pet peeves as a visually impaired person. Basically nothing scales right for me anymore. Apps and websites designed for desktops have such insane padding that when I scale them up, basic information is truncated.
By the time they're easily readable for me, 'progressive' websites go into mobile mode and do things like collapse their (non-resizeable) sidebars. Last week I tried to cut down on excess padding in a sidebar by resizing it and literally watched it go from 40% excess/wasted horizontal space to completely collapsed and hidden behind another click (and thus unusable with keyboard friendly addons like Pentadactyl).
User styling can fix some websites at a high cost of fiddling with the layout
But we do need some a shift away from this awful low density design paradigm
If you live in the US you may have an ADA case against whoever does the website. Many other countries have their own version of that with different rules.
I do keep Outlook and Teams open basically all the time, and full-screened, yes. Here I can only counsel that having multiple smaller monitors was a wiser investment dollar per dollar than one big monitor.
