Looks like you already have a lot posted on this thread but I'll give it a go anyways, If you're looking for something with sort epiodes but over 100 pages Then My comic TLC might be a good fit!
The comic is about a young girl that gets kicked out of an orphanage for her unpredictable powers and ends up getting taken in by a shapeshifter into a mish-mashed adopted family. she has to learn what it means to be herself, be part of a family, and uncover whatever the family's butler is hiding before its too late!
The comic has got aspects of modern fantasy, mystery, found family, and slice of life (as well as tiny bits of science fiction but thats far from the main focus). I'd probably rate it at PG-13 (specific Pages with PG-13 content are flagged as such in the episode tittles as well)
Heres the link if interested!
