Just today I was thinking that some clean/mixed-vocal djent (AKA "technical groove metal" but nobody's gonna call it that) artists sound like a modern extension of nu metal, albeit with more technical chops than mainstream 2000s rock/metal had.

You might like Periphery. They're probably the biggest djent band right now and have a new album out soon.

Monuments have a bit of a rocky discography overall, but if you can get into harsh vocals then 2014's The Amanuensis is really good.

Unprocessed are a German band treading the line between virtuosic musicianship and poppy metal, which is a really weird combination. Great production; often lacklustre lyrics but if you're coming from nu metal then that shouldn't be a problem.

I don't think Sleep Token really take many direct cues from 2000s rock/metal, but they're worth mentioning anyway as a major up-and-coming artist right now. They've got a new album out soon as well and the singles suggest that it'll be pretty diverse in sound.
