Portrait takes more of the screen than square
1080 × 1350 occupies about a quarter more vertical space in a feed than 1080 × 1080, for the same content. On a phone, screen space is attention.
Crop, do not pad
Filling the frame and cutting the overflow keeps the image sharp. Adding bars to preserve the whole picture wastes the space that matters and reads as a repost on most feeds.
