Also make certain that the brake cable housing ends are properly prepped and with the correct metal ferrules installed where required. https://www.sheldonbrown.com/cables.html#cutting

If they are not flat and well-fitting they will compress under stress, lengthening the pull required. You might also consider inline cable adjusters to precisely dial-in the cable tension just short of the pads rubbing.

And to jimc101's comment, Microshift products are good performers (I perceive no difference from Shimano) and good value.
