If you can raise your upper body a little higher, e.g., put your hands on a step, a regular push up might be easier. A regular push up also works your core more.

Hand placement can alter the body part you are working:

Elbows close to body - working back of arms more (triceps) This is harder

Elbows flared out - working pecs and anterior deltoids

Hands closer together - inner pecs and triceps

Hands further apart outer pecs and anterior deltoid

In any of these positions, be mindful of stress to your elbows and your shoulders. The hands close together can be tough on the elbows & hands further apart can be hard on your shoulders.
