A few recommendations

Grand Magus is closer to the Ozzy style, especially if you’re into the Black Sabbath stuff.

Cauldron are a really solid classic sounding heavy metal band.

I would love to recommend Scorpion Child But it’s been a decade since they’ve released an album so I’m not sure what’s going on, there.

Haunt are my favorite modern band who I think fit your style. These guys just keep getting better so far
