Recommendations for plates and utensils for soon to be 1 year old

My LO has 4 teeth and can feed herself just with her hands. When I would hand her her plastic spoons, she'd just throw them around and she seems to do something similar with plates so we just put bits of food on her highchair and have her pick up the food to eat. I was thinking of suction plates to avoid having her throw the plates on the floor and what is the difference between purchasing plastic and metal utensils for her to practice with? Also I want her to start practicing drinking from a cup or a training cup of some sort to learn how to sip and drink on her own. She tends to throw cups on the floor as well, so we hold her sippy cup for her to drink. But I'm worried about doing everything for her and depriving her of trying to be independent. Help!
