What's the best smart display for a family calendar?

Verified-purchase reviewers and specialist communities like r/smarthome and r/adhdwomen point to the Skylight Calendar as the dedicated option, since it syncs Google/Apple/Outlook calendars into a color-coded touchscreen built specifically for this use. The Echo Show 15 and 21 can show a calendar but Reddit threads repeatedly complain the home screen times out and reverts to ads or Fire TV.
