How much of the vertical resolution a core will use depends on its resolution. While many arcade cores are theoretically 240p they don't necessarily use all of that.
So it won't necessarily fill vertically unless you compromise on integer scaling or there's a meaningful crop solution, as mentioned by FoxbatStargazer.
And it won't be the same, no. 1200p allows for 5x scaling while 1080p will be 4x or needs a dynamic crop feature to reach 5x (AmigaVision is a good example of that).
Even with today's decent buit-in scalers, integer scaling looks better. Add scanlines and shadow masks and it becomes even more important with integer scaling.
Perhaps I wouldn't mind non-integer scaling so much on my LG C-series OLED in my living room, but then I think that's better reserved for modern gaming like my PS5, and I prefer the 24" 1200p for MiSTer.
I can't find many 1920x1200 monitors with 48-75hz VRR range.
See the link I posted further up.
There is one Iiyama monitor but it only does it over DisplayPort not HDMI.
Depending on the type of VRR type or monitor, it's often via DisplayPort, so you get a HDMI > DisplayPort converter or cable.
See the article I linked to earlier.

With freesync support on mister now I would also keep an eye for that, with a range at least 48-75hz or so. That will let you experience a lot of cores at weird refresh rates optimally (PAL stuff, arcades, wonderswan)
Are you experiencing problems with PAL or odd refresh rate cores?
I don't use VRR and I have no problem with PAL or NTSC cores or settings, or any odd refresh rate. So I can experience all of those cores just fine without VRR active.
VRR seemed to make no difference in my tests (in the link mentioned earlier) so I skip it to avoid any additional lag as well.
Wonderswan at 75.4 Hz will default to the 60 Hz compatibility mode even with a 75 Hz screen (in my tests) since it's too high, VRR didn't make any impact on that either in my test.
