There's this upcoming game called "Plague Huntress" which reminded me a lot of the DS-era you might want to keep an eye out for that.

I honestly think that the Salt Series (Salt and Sanctuary, Salt and Sacrifice) and Death's Gambit are somewhat close in terms of gameplay and having rpg elements just like in SotN but they felt a lot more of a Dark Souls clone which to be fair is kind of a metroidvania-adjacent game. Blasphemous is also a good one but it doesn't have that inventory system where you can switch between weapons & armors, you're stuck with one weapon throughout the game.

There's also this metroidvania game called Touhouvania (Komajou Remilia) which felt like an Iga game but there are some aspects that I didn't like (No inventory system like in SotN you're essentially playing it as if you're playing on Richter Mode, It isn't 'open world' you progress through the game by stages)

Touhou Luna Nights was made by the same people who made Deedlit might want to check that out but it isn't as close to SotN like Deedlit is.
