These could be summarized/reduced
1.) More Immersive World: includes your #2, 3 and 7
1a: Night and day cycle, even if it was a binary "dead of night or middle of the day" system
1b: Camp locations change based on your location and/or you set camp right where you are
1c: I guess the multitude of items on trash mobs goes here?
2.) Resource Management: your #6,10,11
2a:More short rests to balance short-vs-long rest classes
2b:Camp should cost resources to prevent long rest spam (higher difficulties only). Optional: traveling to camp and sleeping risks random encounters
2c: Fast travel to camp is limited when in dungeons/dangerous places.
3.) Balanced Combat Corrections: your #4, 5, 8
3a: IF Larian wants to HP bloat and AC reduce, they also have to reduce enemy Saves and correctly scale spells that affect HP
3b: Height/backstab should not grant Advantage. A numerical bonus, perhaps.
3c: Surfaces are OP, making cantrips too powerful and especially nerfing Concentration spells. Do any/all of: Reduce the number of times surface damage ticks, allow saves for no damage, cantrips either create surface or do damage
I didn't include your #12 as I haven't seen much conversation regarding it, and personally meh. 5e doesn't have a big focus on traps/crafting honestly.
I didn't include your #9 because I just assume Larian will implement it when the full game releases (and it doesn't fit easily into one of my 3 categories)
