There is a boss rush run and gunner on the SNES or Mega Drive. I don’t remember the name. Will edit when I find it.
EDIT: Got it. It’s called “Alien Soldier” (very generic). It is sort of a hidden gem on the Mega Drive / Genesis due to the name being so underwhelming.
Furi.
Mega man 11
Really any of them, the first x collection is great.
Titan Souls. It’s hard as hell too.
Hollow knight pantheon
Pretty much any megaman but I’m partial to zero because of the sword play, but they all have a boss rush at the end
Salt and Sanctuary

Super meat boy, the original one, not the new Super meat boy forever. Challenging but fun as hell
I think from what I remember, enter the gungeon has a boos rush and is also got quite similar boss attacks in a way.
You play the DLC too?
Binding of Isaac
