[Star Wars] Did Obi-Wan pick Tatooine because Vader would avoid the planet and connections to his past, or because he wanted Luke to have what Anakin didn't; a stable family and upbringing?

It's full of sand. Anakin's natural enemy. 

Jokes aside, it's likely both, since Tatooine allows him to hit both wompas with one stone, since Tatooine for Vader is full of attachments he'd rather leave behind - and by this time he likely did, and won't give the planet a second thought, and because Larses are the only living family Luke still has that can raise him like a normal person. And the planet is a huge desert, it's not hard for Obi-Wan himself to get lost there and keep an eye on Luke.
