Everything I was going to say has already been mentioned, some numerous times: The Expanse, Battlestar Galactica, Babylon 5, Firefly, Farscape, Fringe, Altered Carbon season 1, Dark Matter, Killjoys, Twelve Monkeys.

So may I offer up Timeless and Warehouse 13? Both character-focussed and on the lighter side, but also dealing occasionally with some pretty deep character arcs. And they were just FUN (especially Warehouse 13).

Also, more recently I really enjoyed The Peripheral (though I would have preferred a proper ending, rather than the dangling threads we were left with - especially since, at the time, we didn’t know if there would be a second season).

ETA: Oh, and I haven’t seen any Star Wars shows mentioned besides Andor - which was admittedly fantastic. But my favourite Star Wars TV series are SW: Rebels and SW:The Clone Wars. The latter because it added so much depth to Anakin and Obi-Wan, along with many other characters, and also gave us great new characters like Ahsoka and Wrex. And Rebels holds a place in my heart - many of my favourite Star Wars characters come from that series (Hera, Kanan, Sabine… and Chopper!)

I liked the Silo series too. Hoping to watch the TV adaptation at some point.

Some of my favourites:
Murderbot series by Martha Wells
Imperial Radch series (Ancillary Justice/Sword/Mercy) by Ann Leckie
Vorkosigan Saga by Lois McMaster Bujold
Dogs of War duology by Adrian Tchaikovsky
The Expanse series by James S A Corey
Monk & Robot series by Becky Chambers

I’ve not read the Xeelee series so can’t say if there’s any similarities, but they are all excellent sci-fi series and well worth your time.
