While Aerich's father is mentioned on page, we don't get much of their relationship beyond 'a rival disgraced him, he killed himself, I'm out for revenge'. So, probably at least a 'respectful' relationship before his father died, if not good?
Penric's father is also mentioned on page, but Pen is much closer to his mother. Like, not a bad relationship, but they weren't close. (Pen has two older brothers and four older sisters, and he was the weird bookish one.)
Let's see, I also play Simon from October Daye, and another 'seems to have a good relationship with his dad'.
For OCs, I have Bel and Ilphyl, who are Forgotten Realms drow siblings. Technically they do not share a father, because their mom was really trying to chase down why she kept having boys. What Bel will answer depends on if you want the closest he has to a legal father or his bio father.
Both tended to have their maternal uncles (general term for 'men of the prior generation), and older brothers/cousins as male role models.
As for characters as fathers, both Pen and Simon have kids. Both are devoted dads, though Simon messed that up by 'spent a century under mind control to try to bargain to find his missing daughter'.
(It is canon that if you give Simon a child he feels responsible for, he will do his best to be a good dad -- in the illusion Titania creates where he raises his ex-wife's half-human daughter, she considers him Her Dad.)
(Again, with OCs, Bel was a primary male role model for Ilphyl, but it went badly because giving an adolescent who had a shitty childhood care of their equally-unwanted-by-mom younger sibling, neither does well.)
I've just finished reading the Penric stories recently! I loved them.
Woo! I think a new one is out in July
I haven't gotten Assassins of Thessalon yet, I keep waiting for them to get released in book form. but ahhh so nifty.
