Wow, I am very sorry for you, your wife and family during this awful time. May he rest in peace.
Sister and I had to take lead on dad's funeral 11 years ago. It is a fooking racket and expensive as hell. If I can offer one bit of advice it's this. Know what it will cost before you agree to anything. As I suspect it is for most, it was a blur for us when we went through it. The Funeral Director will literally agree to do anything you need. Services, casket, a vault, flowers, food, pastors, soloist, etc. It all costs way more than you think. We had a pretty modest deal for my dad and it was still $18,000. That was small town NW Iowa prices too.
There are going to be a lot of people around the next week or so. People will be bringing food, offering to help, etc. After services are done, they go away and reality sets in and the grieving really starts. The last thing the family needs is a surprise enormous bill.
Good luck, brother.
Edit - The director at the funeral home we used was a good friend of my sister. While we weren't happy with the total cost, he let us make payments while the estate was being settled. Stretched it over 10 months which was a huge help.
