I have the thin Spigen case on mine, and it works great. https://www.amazon.com/gp/product/B07GQCN63S/ref=ppx_yo_dt_b_asin_title_o08_s00?ie=UTF8&psc=1
For screen protector, I went for the premium option: https://www.amazon.com/gp/product/B07JQT17Q4/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1 For this one, TAKE YOUR TIME. It's pricey, so be really patient, as the process takes time, but the results are outstanding for me. Doesn't attract dust or fingerprints very much and touch sensitivity is great. No rainbow effects either. Admittedly, I messed up my first one due to going too quickly, so I had to order a second one and redo it and it was flawless the second time.
