What's the point? 
Is he just going to smurf and pretend to be a weak F class adventurer but then will jump at the first opportunity to show how strong he is to his first female companion setting up a harem where all his companions know how strong he is but all the quote unquote bad guys he faces will underestimate him? Or is he just going to go full beta and secretly hides his powers to "live a slow life" (but not really) like all the other copy paste isekais like it?
You know what would make a better story? If he actually didn't retain any of his ability or talent from his previous life, falls in love and starts a family only to have that all taken away. Seeking vengeance he decides to train as hard as he can only to realize that no matter how much he struggles it was simply fruitless as his new body truly has no talent for it. Bearing regret at the decisions he has made in his past life, he would rather of died at the apex alone not knowing this loss instead of reincarnating and experiencing this hardship. 
Oh that's right, this is wish fulfillment, no one would want to read something that depressing.
