Three months ago I opted for a MacBook M4 and OpenSCAD runs extremely well
on it.

And, with the recent announcement that Microsoft is no longer going to be
allowing local accounts on WIN11, I am very happy that I made the switch to
Mac.  Is it perfect? No, of course not! But, for OpenSCAD development, it
works very well for me.

A while ago I switched to an iMac M3 (from an earlier Mac). Around the same time I enabled Manifold (which is now default.)

Between the 2 I no longer have to think about performance.

Another thing about the iMac is that the screen is excellent for the money. I couldn’t find a comparable monitor for a reasonable price. I upgraded my second monitor to a BenQ and it has settings to match the color profile of the Mac screen. The better matched screens removed a source of regular annoyance.

I have two TCL 43" 4K TVs.  They were $200 each from Costco.  I love
them.  I have a ridiculous amount of glass in front of me, and it's high
resolution.

They do seem to have a problem with reaching 4K at 60Hz; I run them at
30Hz.  I don't have any use cases where that's an issue.  When I try to
drive them at 60Hz they seem to usually negotiate some non-RGB color
scheme that subtly messes up the color, but at 30Hz there's no problem.

Plus they have decent speakers.  Maybe not audiophile-class, but plenty
good for beeps, watching videos, and Zoom calls.

Same basic setup as Jordan's, only with 47" or 48" 4K TVs, set to a
slightly lower resolution.

We are living in the future.

My preference is for the highest resolution I can get in terms of dots per inch. Something close to an iPhone’s screen. The finer dot pitch is really easier on my eyes. That means staying with a medium size monitor, Th imac is 24 I think and the BenQ is 27.

My math puts my displays at 102dpi.  Not print quality, but not bad.  I
don't perceive the pixels in text.

It looks like iPhones are 300-500 dpi.

Note that the required dpi depends on the  viewing distance; you need
more dpi if you are viewing from closer.  A quick measurement says I'm
at 32" from the centers of my monitors, and closer to 38 from the
edges.  It's better to measure arc seconds per pixel at the intended
viewing distance, but that's harder.

As an older fellow, the super high res displays are wasted on me.  I
can't get close enough to them.  I work at a distance of between 3 and 4
feet.  I would say 100 dpi is more than enough.  I imagine that the
phone market is being driven by the under-40 crowd, who do not yet need
bifocals.  Similar comments about the light-gray on dark-gray designs: I
yearn for contrast.
