What's your recommended survival crafting game to play solo?

Basically the title. I think I've come to accept that as basic as it sounds, this is one of my favorite genres.

The issue I frequently run into is that so many of them are designed around PvP and / or Co-Op. Like ARK, I love the idea, but most of the mechanics are for PvP servers, which I have zero interest in.

Funny enough I'm not too into true survival games (Green Hell, The Forest), as I kinda enjoy the whole "Combine iron with two sticks and make an automatic weapon" progression of other games in the genre.

Obviously I've played Minecraft & Terraria, but also Subnautica, Palworld, Satisfactory (sort of counts), and NMS and enjoyed all of those.

Project Zomboid seems like it has too steep of a learning curve for me to get into.

I tried Astroneer, but the utter lack of base building and organization drove me up the wall.

EDIT: Forgot V Rising, which I also enjoyed solo, but it's definitely built with a PvP server in mind, which kind of makes progression in solo feel like you're aiming for a goal that doesn't exist.

I appreciate everyone's suggestions, I think I may give Raft or Project Zomboid a go.
