I also appreciate how his family plays a role. (It is probably hinted at in the title, “Dad’s Been Reincarnated,” not “I’ve Been Reincarnated,” so you’ll probably expect to hear from his kid.) A lot of times people in the past life are present just to set up the character’s personality/outlook and never brought up again. I don’t mind that, but seeing something else done is still cool!

Also, double points for what seems like a healthy and peaceful family relationship. Mining family dynamics for drama is very easy (and totally understandable given the sheer amount of people with at least some amount of familial strife in their lives), so it is always nice to see a protagonist with a healthy home life.
