The best solution I have found for my friends and family is the Brave Browser on the desktop, and Firefox Focus on mobile. Neither are perfect, you do have to give up some granular control, but I feel they might be the best solutions for the layman at this time. I've also heard that DuckDuckGo recently made a simplified uBlock time add-on. Haven't had a chance to play with that much however, maybe someone can chime in.
