Cherry trees (and other tree fruits) are usually a hardy root stock that doesn't make good fruit, grafted with stems that grow nice cherries but aren't strong healthy trees. So you can try planting the pits but you'll probably get a spindly bush.

Watermelon seeds will grow if they are ripe black ones, look for an overripe melon.

Tomatoes often grow well, I've had success just smooshing the softest guy from a pack of them into some soil and watering. Especially "grape tomatoes." Be sure to give them a cage to climb.

A planted strawberry will grow lots of little sprouts, you should cut it up a bit to spread them out. Again, you want the one that's a bit overripe.

Which is why you don't plant the green bell pepper, you plant the red one.

I've got cherries and blackberries that are growing faster than I want. You can have some of mine.
