Or best of both worlds?
As much as I love Wales and where I live there are so many stunning places all over the world - and an ultrawide, especially when you’re doing something like writing (which I do a lot!) really can make a difference to how you feel (so great for your general health and well-being).
The only downside is that it makes you want to get out there …which isn’t really a downside if it gets you to actually do it 
One day I’ll figure out what triggers them and then turn them off…
Actually, I did try spaces once when presenting full screen - I wanted to hide all my normal mess on another screen. It didn’t go well - pop up windows in Excel only ever end up on Space 1 (only discovered when the presentation was underway), so I had to flick back to the mess anyway, and probably induced sea-sickness for the poor folk watching with the back n forth.
Did you also say you have rotating wallpapers? I would spend so much time thinking: “oh, where’s that?”
Technical hitches always make talks a bit more fun 
but yeah you can turn off Group windows by application which I recommend.
I am surprised more people don’t use Spaces, I find them invaluable. Here’s my settings for them:
And Hot corners:
I always have them in this order:
[Apple Music] [Apple Mail] [Main Desktop]
Then the next Space will be what I am working on currently, and other Spaces could be for other things I am working on but not urgent or continuous. Sometimes I can be working on something (or overseeing something) and it could be ongoing for months, so keeping it all in once Space makes is easy to jump back in to as and when needed).
I highly recommend giving them a go!
I do, every 5 minutes and independently for each Space. If you get your wallpapers from https://wallscloud.net/ they tend to label them, for me I am just happy to see a nice view and if it did make me want to look up and or visit the place, I reckon that’d a huge bonus
