If you're looking for series that really focus on the "character study" aspect, then I would recommend Welcome to the NHK and Tatami Galaxy. Both series deal a lot with regret, hopelessness, and isolation, which I think are themes that might be especially potent given this past year. NHK in particular is a very intimate look inside the head of a deeply flawed person. Sometimes it's hilarious, other times extremely tragic and moving. I happened to come across it at a point where I was very depressed and struggling to find direction in life, and it affected me deeply. Fair warning - the subtitles in Tatami Galaxy can sometimes be hard to follow because the characters talk so damn fast. The very first scene is especially bad offender, so give it a couple minutes before giving up for that reason.
