Hey Arnold! It's a little older but wonderful to watch and subtley shows some serious issues (one character's mom is pretty obviously an alcoholic, even if you never see her actually drinking, but it's not too blatant for naive minds)

Also, Pepper Ann is criminally underrated. It never gets particularly serious or anything, but it's a good coming of age show with a pretty relatable female main character. One thing that's stuck out for me is that pretty much anyone would think she's a pretty cool girl they'd want to be friends with, but she feels hella awkward around most people. Good way to bring up that you may feel a bit awkward, but sometimes you need to fake a little confidence and others may take it better than you'd think
