BG3 should check to see if movement is inhibited by rough terrain, and if so, halve jumping distance to be in line with standing jump rules. I wonder how far BG3 characters can jump, is it really 1' for each point of Str? Seems more.
Sleep at level 1 is 22hp, level 2 31hp and +9hp each level after, however actual level 3 spells often outclass up-cast spells. Initiative order is key to using Sleep well.
I haven't played with level 3 Plant growth, but in TT its area is huge, reduces speed to 1/4 and allies can be exempt.
Entangle is more a spot movement inhibitor. It has a small area effect, though 20' is further than most characters can long jump, and a Str9 wizard can't automatically jump to safety from the middle.
