The comparison to Deus Ex is not off. It's got turn-of-the-milleneum AI, zero exploration benefit, and so on. That's not a bad thing, except, of course, it wasn't going to be that way.
It's not an "open world" but its level design is much more intricately layered than any part of CP2077, including the main mission set pieces. You can even kill important NPCs and it will change the storyline
But Deus Ex (The original) had great benefits from exploration.
If it was like Deus Ex with updated graphics, I’d probably have bought it, but it looks more like The Witcher with a Deus Ex paint to me.
It won't bring it up to modern standards by any means, but have a look at Deus Ex: Revision (https://store.steampowered.com/app/397550/Deus_Ex_Revision/).
