I was running AntiX out of your list on my old atom eee-pc pretty successfully the last 2-3 years. Was using it as a workbench pc with an old vga screen and keyboard connected, and it worked well enough for simple pdf /datasheet reading and terminal sessions.
For specs, I think it was the same cpu but only 1gb of ram. Honestly with 2gb of ram your options are much broader, the one part you’ll run into trouble with is the browser with multiple tabs anyway. I thought to remember there was also a community-maintained 32bit Archlinux variant?
Edit: https://www.archlinux32.org/ that’s the one I believe. It has a more restricted package repo but otherwise is just Arch.
