Switch is best for family use. Always enjoy playing it with my younger cousins and even my older relatives when we have family gatherings. Games we play would be like:

1. Super Mario Party
2. Mario Kart
3. Just Dance
4. Overcooked
5. FIFA
6. Super Smash Bros
7. Asphalt Racing (free)

For old school sake and my personal preference, go download older games from Nintendo online store:
1. The super old and original Mario in Gameboy Color
2. Metal Slug the one we played in PS1
