What Linux would be easiest for an older Chromebook user?

Check the exact model before picking a distro. Chromebooks can have different processors and firmware restrictions, and some older models are much harder to convert than a regular laptop. If it has an ARM processor, many common desktop Linux options may not work. Also check whether the model is supported and how much storage it has.

If it turns out to be a compatible Intel model, I’d start by trying Linux Mint or Xubuntu rather than chasing the absolute smallest distro. A familiar desktop and a browser that still runs well matter more here than shaving off a little memory use. Test it first, especially if storage is limited.

For someone who gets lost between apps and windows, the desktop setup may matter more than the distro name. GNOME has accessibility options such as larger text and magnification, and you can keep the desktop simple with only a few obvious apps. Try the interface with the intended user before committing, since a desktop that feels clear to one person can feel confusing to another.

Don’t rule out using a different laptop if the Chromebook is a hassle. Unsupported hardware, awkward firmware steps, or very little storage can turn a supposedly easy setup into ongoing maintenance. If there’s already a compatible laptop available, setting it up simply and keeping it updated may be the kinder option.
