"It's typical of me" means it's my usual behaviour, however it's not entirely natural to say something is typical of oneself, rather a native would use "typical of" to describe someone else.
"It's typical for me" means...I don't know, in all honesty. I suppose you could say "It's typical for me to get a fine just as I was about to get to the car".
