Rice and Oatmeal Brachot

What is the Rav’s guidance on the brachot over cooked rice and over oatmeal? What about rice noodles or rice crackers?
Oatbread/oat-matza (no wheat, oat being the primary )?

Many thanks in advance for the clarifications!

All rice related products you mentioned are mezonos. All Oats products are always haadmah.
