I believe the OP is (likely to be) more interested in the distance considerations as opposed to trajectory - though there is obviously a relationship between those (loft, distance, trajectory) attributes that may be important to some shots....
44 for low shots, 50 for medium and 58 for high.
As a fan of Dave Pelz's wedge philosophy, I'd advocate his 3 wedge approach - using his clock technique to swing to calibrate and execute for the required distance. The lofts required to get a suitable spread should 'pop out' from practice - which is something that is required to use wedges properly anyway!
