We love Tim Tracker and SeeYaReelSoon - they are both definitely family friendly. The Must-Do Disney videos that play in the resorts are on YouTube too, which is great for like a highlight reel of all the parks.
We love watching ResortTV1 which streams live from the parks every Friday at 6PM Eastern (and sometimes during the week with surprise live streams). Josh and Jenna have a great family-friendly stream. Currently watching the live Magic Kingdom stream and singing along!
I watch Tim Tracker, DFB, Dis Unplugged, WDW Couple, Prince Charming Dev, TPMvids
I watch Disney Pins Blog and DisneyKittee a lot too, they're probably in my top 5. They are however more pins/merchandise focused so it might not interest everyone. But they do go to parks and resorts. They unbox mystery sets in collaboration often which I love.
