Our Area Presidency has allowed (actually encouraged) using technology during this time. Variations abound in what each unit needs, and what each unit feels comfortable doing. My congregation's implementation has been a simple Zoom worship service each Sunday, with a single speaker book-ended by congregational hymns (everyone muted, words and music shared on-screen). OK, actually two worship services, one in English followed by another in Spanish, due to our mixed congregation! We were instructed to not include anything regarding the sacrament ordinance in our virtual service, and to ensure members understood they could choose to just have their own home-centered worship service, or just attend the virtual service, or do both.
Our members have also self-organized into a twice-a-week Zoom "Come Follow Me" study group (again, actually two study groups, one in English and the other in Spanish). Primary has twice-a-month Zoom activities that are well attended. RS does twice-a-month Sunday Zoom meetings (again, separate English and Spanish), EQ nothing. Our Youth have been having weekly Zoom activities, which at first were fairly successful, but our Youth are losing interest and we are anxiously awaiting the ability to have any kind of limited and responsible in-person youth activities. We also had a Mission Prep course via Zoom, which was great multi-week experience for our older youth and RM's (it overlapped with our missionary who was at-home quarantined after returning from Mexico, but could still participate virtually).
I wouldn't say any of what we're doing is "best practices", but I would say that it has been helpful for our specific needs.
