[Genuine Realist]

I endorse the Night Manager.

If you liked the Tunnel, you might like the original, The Bridge (2011), better.  Instead of the murder taking place in the Channel Tunnel between and featuring British and French detectives, The Bridge takes place on the Bridge (duh) connecting Denmark and Sweden.  The Danish/Swedish cultural differences are very interesting, though of course it plays heavily on stereotypes.  And I have been very partial to Nordic murder series (I would put a plug in here for Wallander, which is a British production).  I think there are four seasons of The Bridge.

Some other favorites:
Luther (featuring Idris Elba, who goes from Baltimore drug kingpin in The Wire, to British cop in Luther); still waiting for him to be the next Bond
Casa de Papel (the Spanish name, known as Money Heist in English)
Fauda (an Israeli series about the Mossad)
Tehran (just started it, on AppleTV+)

Agree on Fauda - have watched every episode.
And I also loved Ozark, even though twisted and disturbing in many ways . . .

We really liked Ozark, and the Night Manager ... Teheran is really interesting, not yet fully available ... and for not in English, Money Heist, the Bridge, Fortitude, Occupied, Berlin Station, Trapped, Valhalla, Lilyhammer, Nobel, Ragnarok (a pattern of Norwegian there, not for any reason except good plots and interesting characters)  ...

After Breaking Bad, the best thing I've ever seen on television is Babylon Berlin, on Netflix, now in its third season. The production values are sensational and every penny shows on a good sixed LCD television.
