First-time homeowner unsure how to handle minor repairs

I bought my apartment about year ago and I’m still figuring out what’s worth fixing myself versus bringing someone in. Right now I’ve got a few drywall anchor holes, some paint scuffs, and one small hole in a wall that I’m debating what to do with.

For those who’ve owned a place for a while, do you usually handle this kind of stuff on your own, or is it better to hire a pro even for small repairs? Mostly trying to avoid making things worse while I’m still learning.
