Yeah, on the web, just use font-family: sans-serif (or, now that browsers don't systematically default to a serif font anymore, just nothing at all) and let the user see the default font, or the font they picked. It also improves everything else in contrast with a web font: it saves bandwidth and therefore cost, it saves page load time and therefore SEO and user retention. And it's not worse, nay better, than the font you arbitrarily picked. The default font needs to be dyslexic friendly on a dyslexic's computer if it's not already, and it should be the OS's job to ensure this. I am afraid there's no one size fits all wrt fonts and accessibility because I suspect different conditions have different requirements, so you can't pick yourself as a web designer. We indeed need dyslexic friendly fonts among others so dyslexic people can configure their devices with one that they like, fonts that are indeed actually proven as being effective as another commenter said. No proof: it didn't happen.
