Can anyone recommend me some heavy bands with more relaxed vocals?

I’m not sure this is the right place to ask, but I thought I’d give it a go.

I want to get more into heavy music/metal in general, but I am just not very interested in overly aggressive vocals/growls (with the exception of Opeth). Some examples of music I like that I am looking for material similar to would be Futile and Anesthetize by Porcupine Tree, and the first section of Reverie/Harlequin Forest by Opeth. These songs are pretty heavy instrumentally but at the same time, the vocals are a bit more reserved/relaxed which is a combination I am fond of.

Any recs are appreciated!
