The novels listed below also have MCs who transmigrated from an apocalyptic world, so I think you might like them.

https://www.novelupdates.com/series/i-was-raised-after-being-a-mermaid/ <— MC has the water ability and transmigrates into an interstellar world and becomes a mermaid. His background doesn’t seem to affect him except to explain where he got his ability. I sometimes forget he comes from an apocalyptic world. It is a cute read with some serious undertones.

https://www.novelupdates.com/series/stone-age-husband-raising-journal/ <— One of my favorite BLs. The MC is a plant ability user who transmigrates into a primitive world where humans have beast forms. He’s very powerful but has severe PTSD about fighting things, so he keeps his strength secret. It’s slice of life and has quite a bit of cooking. It is very wholesome.

https://www.novelupdates.com/series/i-turned-into-a-little-white-face-after-i-returned-from-the-apocalypse/ <— MC transmigrates from the zombie apocalypse to a “peaceful” world facing an infinite flow apocalypse where resources can only be gained through games. I don’t remember much, but I vaguely recall it being funny.

https://www.novelupdates.com/series/shh-theres-a-beast-in-the-imperial-palace/ <— It’s been a long time since I read this, and I don’t know if I finished it. Both the MC and ML are ability users from the zombie apocalypse and transmigrate into an interstellar world. It’s written by the author who wrote “The Zombie Emperor’s Domesticated Cat” and “Number One Lazy Merchant of the Beast World,” both of which are BL stories I liked a lot

This last one I’m about to list doesn’t fit this category, but the MC transmigrates from a sentinel/guide wasteland-like world to an interstellar omegaverse. It has some similarities to “Villain Alpha is Pregnant,” so I think you might like it https://www.novelupdates.com/series/crazy-tyrant-sentinel-transmigrates-as-a-flower-vase-omega/
