Can't remember how many of these are just PS5 or shares with PS4, but.....
The God of War sequels are great if you have any interest in the franchise.
Armored Core: Fires of Rubicon. If you can get past the filter helicopter.
Stellar Blade is good, and there's been a sequel announced, although it's not due for a couple more years.
Code Vein 2, while far from flawless, is a good Soulslike action game. If you haven't played the first Code Vein, it's also worth a look, but the stories aren't at all connected, so you don't need to know one to play the other.
Control, especially the Definitive Edition with both DLCs included, is basically a third-person shooter in a setting inspired by the SCP Foundation.
Digimon Story Time Stranger is a solid, if grind-heavy, turn-based RPG with plenty of monsters to collect. The previous Cyber Sleuth games are also good.
Afterimage is a solid Metroidvania with mild Soulslike elements.
