I think the closet games would be Ryse Son of Rome, Quantum Break, Hellblade, and Plague's Tale. I would, however, recommend that your friends maybe try games outside of their comfort zones or genres they don't typically dabble in. That really is the true appeal of Game Pass, in my opinion. I would recommend games like the Ori games, Death's Door, Tunic, Donut Country, just to name a few.
Haha let me tell something funny. That's what I did, and for sure I think it was for the best.
I used to have only PS Consoles (Have more than one console in Brazil is expensive as hell) and I made the change in the Xbox One Era. (hahaha not the best one to made the change). I was not a fan of uncharted and TLoU in PS3, with X360 getting JP games at the time (My personal taste at the time), I thought that getting a Xbox One would be a good idea. (hell I was so wrong about the JP games).
Yeah the JP games was a mistake, a bad one. But in the other hand, I got to know a lot of others games and it's was really really good, they were games that I definitely would not play if I stayed in the comfort zone. And when GamePass came, well, it was awesome. I never had played so many games like that.
So, I'm glad that I made the change and left my comfort zone (yeah I missed some others games that I would liked to play like Bloodborne, FF7R and Persona 5) but at the end it was for the better.
Trying things outside your comfort zone can do marvelous things, but I will be sincere, not everyone is willing to make it.

Ps.: Yeah, I still don't have a PS4/5, but now I got a better job, I will be getting one in the next year, when supply gets better I guess. I got a Series X, it was expensive as hell, so no way to getting a PS5 at the same time. (And PS4 cost way more than a Series S in Brazil, currently, more than 1000R$ ~ 192,50USD so it not makes sense to buy one anymore)
Ps2.: \o/ Persona on Xbox!
Ps3.: No FF7R is sad.
