Attend? or arrange? Funerals not being attended these days. If you are to arrange one, contact a funeral home and tell them what you want. Also check out "Dying with dignity."
I had experience with this 2 weeks ago, supporting a family member involved in the arrangement process. First and foremost, sorry for your loss.
The Funeral home and church selected for the funeral took care of pretty much everything. This included a select 5 family members attending in person and for the 200-300 who also attended did so virtually through the online services provided by the church.
Take care with the difficult task in front of you.
