Samsung are slowly becoming like Apple, trying their absolute best to copy Apple. At one point Samsung was Samsung and Apple was Apple. Meaning, Samsung had its own features like micro sd card, charger in the box, every model was qhd resolution etc. Now they are slowly removing features and putting the best features on only the ultra model. Even then the Ultra has removed features also.
I'm happy right now with my s20 ultra as it has a micro sd slot and had a charger in the box. The new s21 series have removed alot of these features.
I would say stick to the s10 plus, it has everything you need plus the headphone jack, headphones, charger, qhd screen, great camera, mst, glass body etc
