Just got my note 10 plus today, and I ordered this one -

SUPCASE Unicorn Beetle Style Series Case Designed for Galaxy Note 10 Plus/Note 10 Plus 5G, Premium Hybrid Protective Case 2019 Release (Black) https://www.amazon.com/dp/B07VDK82GQ/ref=cm_sw_r_cp_apa_i_6oWFDb36WJTFR

Gives it a bumper look while also protecting the back and showing off the finish. Seems like it's an established design across multiple phones, and one YouTube reviewer tossed it from head height onto concrete and it didn't have a scratch. Hopefully it's actually good.
