A common answer is that slightly longer than normal lenses such as your 75mm FF equivalent are great for portraits. Two reasons for that are:

1. The angle of view is about right for filling a frame with a person from a distance that won't cause a lot of perspective distortion. If you stand close enough to your subject to fill the frame with their face using a wide angle lens, the center of the face will be exaggerated -- you'll give them a larger nose than they really have. Long lenses, on the other hand, do the opposite: they compress distances, making subjects look somewhat flat.

2. Less important, but still a consideration, is that a normal-ish lens puts you at a distance that's comfortable for most subjects -- you're not sticking the camera right in their face, nor are you so far back that you need to shout to be heard.

If that's the kind of answer you're looking for, then perhaps you don't need this lens since you don't shoot portraits.

Keep in mind that lenses don't care about the subject and will happily shoot whatever you point them at, so rather than thinking in terms of categories, consider whether you have a need or want for a lens with a 26 degree angle of view.
