Abbott Elementary - Mockumentary style sitcom about teachers in a US public school.
Brassic - more of a drama comedy, but you know, wikipedia is willing to list it as a British sitcom. It’s about a very broke guy with bipolar doing petty crimes with his buds, and is truly top notch.
Cavendish - Canadian sitcom about two brothers returning to their hometown in PEI for the first time since childhood.
Dead Pixels - British sitcom about a gross gamer girl obsessed with an MMO.
Derry Girls - Irish sitcom about teen girls in Derry during the Troubles.
Detectorists - British sitcom about two guys whose life passion is their hobby as metal detectorists.
Everyone Is Doing Great - not entirely sure if this is quite a sitcom, but it’s about two actor best friends who used to be heartthrobs on one of those vampire supernatural romance shows, but now they are struggling to have careers after the show.
Friday Night Dinner - (first aired a little over a decade ago, so this is pushing the limits of your request, but it ran for years) each episode is a different Friday night dinner for this Jewish family in Britain, with a big focus on the friendship/pranking of two adult brothers.
Go On - (also a bit over a decade old) guy joins a grief group after his wife dies, and the group is an eclectic bunch.
Mohawk Girls- Canadian sitcom about Mohawk girls on the rez.
Nirvanna the Band the Show - Canadian sitcom about two guys who want to play a gig at the Rivoli (famous Toronto venue) but don’t actually have a band.
One Big Happy - Lesbian and her best guy friend/roommate decide to have a baby together.
Plebs - British sitcom set in ancient Rome, pretty goofy but I have no idea what you consider “good” in terms of a sitcom.
Single Parents - this one is like the name suggests; a group of single parents who all sort of work together to watch each other’s kids and in the process become friends.
Vice Principals - two teachers compete to become principal of the high school they teach at (which also requires them to conspire to unseat the current principal).
Wilfred - This one is a remake of an Australian sitcom, but Elijah Wood plays a guy who tries to commit suicide and then starts talking to his neighbour’s dog who appears to him as a grown man in a dog suit.
I haven’t watched this one yet, but Rob Wells (Trailer Park Boys) has a new one this year called The Trades about working in an oil refinery.
