Hi. If I understand your problem correctly, the two-device limit and your employer's restrictions are making it difficult to use Evernote, and you don't see a need for it. Indeed, if you are unwilling or unable to pay for the premium service, and your employer is preventing you from making full use of it anyhow, then you can either:
(1) use Evernote on your computer with work-related documents in an offline Evernote notebook or
(2) pay for Evernote and just keep your work-related documents on your computer at work
It may be that you don't need Evernote. Personally, I find it to be a useful app. I particularly enjoy the ease of input, editing, and file organization (I do very little organizing, because the combination of robust search options, tags, and handwriting recognition make it possible to get by with very little organization). I don't mind paying for an app I use every day. Your mileage may vary.
In fact, after COVID-19, I've found myself relying even more heavily on Evernote. I have to go into my workplace to work (I am in a region with minimal restrictions), I have to do work at home (we had more serious restrictions up until a few days ago), and I need to do child care while somehow doing work. Work has seeped into everything--it was always a problem, I guess, but now it seems inseparable from everything else. I enjoy my work, but... yeah, I am kind of looking forward to at least making an attempt at separating my private and personal life. I think we are all being asked to wear multiple hats at the same time these days, and Evernote makes it easy for me to go from device to device working on projects in tiny chunks appropriate to the limited time I have to focus on projects. Even if I am suddenly interrupted and have to rush off to do this or that, my work is right there in my pocket ready to be resumed when I have a moment.
In other words, it seems to me that Evernote is uniquely well-suited to our new post-pandemic lifestyle, assuming you are willing / able to pay for it, and you can work around the limitations (my list of Evernote's shortcomings in the context of my work flow has been posted repeatedly here over the last decade, so I won't belabor those points).
