My daughter's (who is 10) favorite game is Champion's Pub. Although it isn't a great game for a small collection.
We own many of the games that you mentioned. We had a WOZ, but sold it since I thought my daughter would like it (she didn't).
I think Medieval Madness is probably the best all-around family game. Although you may want to put it in family mode. Spiderman is also a pretty good choice... it is relatively straight forward. We love our JP, but it is a bit complicated for kids. TZ a great game... but also tough for kids to learn.
Honestly, you can' go wrong with MM. It is top-notch... super fun for everyone... and mostly holds its value.
