"[T]he goal is to give employees a dashboard directing them to company resources in the absence of in-person events, gatherings or town-hall-style meetings."
I've worked at two places in my main career track. Both have company intranet "portal" sites. The latter/current employer actually had two sites, one which was more like social media and built for sharing and the other for "standard" business resources, but they were recently merged and revamped to use Sharepoint to hold all the site files yet still provide blogging, following, etc.
Surely a company's own staff should (but not always will) know what the employees need, especially if they are that engaged in the portal's design and structure, rather than trusting Micros~1?
Then again, the former employer's site was a bit disjointed and not very helpful. Maybe watching people's trends of what assistance/resources they're looking for could help make the experience better. (My current employer already does all that tracking.)
