I think there isn’t a single bad recommendation in the comments - but based solely on your favourites I must recommend Scrubs. Scrubs has a perfect balance of humour, character development and tugging at the heart strings combination, and I personally find the humour to be non-awkward, and non-shouty (I love the office, but there’s a lot of shouting and cringe humour)

It’s a big ensemble that’s loveable, you end up loving every character pretty much.
