2. yes
3. no
Obviously gpu load varies by resolution, fps and game.
You can test how your 1080 will perform using NVidia's DSR.
Enable 2x DSR in the control panel, add your game, choose 4k in the game. Performance will be what you would get with a 4k monitor.
Starfield at 4k - you should get about 2 or 3 fps with that rig.

4K DSR on a 1080p monitor looks better than normal 1080p as images are sharper.
Another point worth noting, is that Bethesda games are noted for their mods. FO4 has 52,000 and rising. Mods add load to the cpu and gpu. So anyone intending to play a modded Starfield, should that be possible, might need better than vanilla hardware. Hopefully Beth can improve Starfield performance.
1. yes
2. no, 1080p is exactly 1/4 of 4k and with DSR you'd still end up with an "as good or slightly better" image
3. no, everything about your current rig is targeted at 1080p. For lightweight indi games sure they'd probably run ok at 4k but for the most part you'd be having to crank everything down to the lowest settings to even get typical AAA games to struggle running at 30fps at 4k.
If you are in the US and happen to be near a Microcenter, you can get a pretty decent deal on a Ryzen 5600X3D, which depending on your motherboard you might be able to potentially re-use that with a BIOS update to support the Ryzen 5000 series.
As for GPUs a 4070 would be worth it over a 30-series equivalent for targeting 4k simply because of DLSS3/DLSS3.5 support for frame generation and ray reconstruction
For monitors, not sure in the 32" curved 16:9 4k range. I switched to a 21:9 display and haven't looked at 4k displays recently
EDIT: that would also be a decent option to get a nice bump in resolution clarity while still keeping a bit higher fps on more titles without having to go crazy on a 4090 lol
3440x1440p is roughly "2.5K" in regards to pixel density.
Here you can try different resolutions and monitor sizes to see the PPI.
https://www.sven.de/dpi/
3840x2160 27" - 163.18 PPI
3840x2160 32" - 137.68 PPI
1920x1080 24" - 91.79 PPI
1920x1080 16" - 137.68 PPI
1920x1080 15.6" (common laptop res) - 141.21 PPI
1920x1080 13.5" - 163.18 PPI
1920x1080 13.3" (common laptop res) - 165.63 PPI
I have a 4K 27" monitor. I don't use any antialisasing in games, and it looks fine. If you look closely, of course the diagonal lines might look a bit aliased, but it's really negligible at that PPI. With antialiasing enabled you lose a lot of FPS, plus the image will be a little washed out, due to the antialiasing algorithm.
I haven't seen a 4K 32" monitor, but I did see a FullHD 15.6" laptop. The text was clearly sharper than on a FullHD 24" desktop monitor. I haven't tested any games though. I did also worked on a ~14" laptop, FullHD, there was not much difference than the 4K 27". My subjective opinion considering what other monitors I've seen so far, not seeing any 137" PPI monitor, is that it's just at the border from sharp vs pixelated text, so you might not need antialiasing in games. I suggest you visit a computer store and see those monitors for yourself. If you can't find a desktop monitor, maybe you can find a 13.3" laptop to look at, it has the same PPI. That's why I've posted those resolutions, to see some exact matches of PPI from 4K and FullHD.
2. By default, yes. It will look worse. Most computer monitor manufacturers are too stubborn, lazy or totally indifferent to offer support for pixel perfect scaling, they usually use upsampling algorithms that blur the image. There are solutions, I don't know them all, actually I've read and tested a bit only one, in GNU/Linux. You can use xrandr to create a virtual output of a FullHD image on a 4K display using the nearest filter that is precisely doing a pixel perfect scaling. Pixel perfect upscaling is the subject to check on the web. You will find many people discussing about it.
3. I don't know. What I can tell you is that most Vulkan games will work fine even on old hardware, not on full details, of course, but with full res textures, which make a game look sharp. I have an old PC with a GTX 970. It was running Dota 2 fine and CS:GO good. I can't help you with any info on DirectX games, but considering the API is not as close to the GPU as Vulkan, you might have a difficult time in new demanding games. You should check, on the web, for any videos showing how well an GTX 1080 works in 4K.
