I'm the exact same way, so unfortunately I have little insight to provide.
The only thing I delegate is design work, because I'm not a designer and know that any designer I hire would be way better than me at design. When it comes to designers, I like to give them as much creative freedom as possible. I avoid nitpicking little things (move this one pixel to the left) and just correct minor issues myself, if necessary.
I'd be curious to hear how others delegate other types of tasks though. Literally everything else besides design (business development, social media, content creation, development, support) I do myself.
From what I hear, developing clear-cut processes that others can review and replicate is the key to a lot of delegated tasks.
