A little late to the party and not sure I have anything groundbreaking but I’ll have a go.
The lists of writing rules always has use active voice but I believe like Jo said it’s more important to tune your ear than to have a list. I do think looking at the why of the rule is important. Active voice paints a more immediate picture because the subject is doing the action. Therefore, reading it puts you into a different state of mind. Reading a passive sentence, though, gives the subject, if used correctly, the connotation of being acted on. A sense of helplessness. Or fate.
As far as editing, I don’t use a program like grammarly but I do a search of state of being verbs and assess the sentence. It helps me focus on particulars. I also search for adverbs, do a word count to see what I overused, search for filtering words—so sort of like the program I assume. To me, it’s helpful to make myself be honest—is this the best sentence or am I being lazy?
