Unity is trash and I'll just leave that alone.
Using Rust for a game engine with wgpu, unless you already know Rust intimately and have used the Vulkan API before, is going to be difficult for you. I recommend you give it a try, but last I checked wgpu expected you to be familiar with Vulkan and is missing comments on most crate types and functions.
You might have better luck with something like macroquad or miniquad, but you'll probably hit a wall and realize you want to do something that the developer didn't think to expose an API to make possible. You're also on your own for sound. Bevy has many components and I know it's popular, but I don't know if it has rendering. Maybe macroquad is the missing piece? Oh, and then text rendering. That's a tough one.
I recommend a couple options: browse lib.rs or AreWeGameYet for game engines that aim to provide a complete package.
For non-rust, recently Relogic gave a bunch of money to Godot and FNA, so I would check those out. That's going to be your quickest start (towards minimalism and performance) that isn't unity.
As far as I'm concerned each side has been just as annoying and incorrect as the other. Have you seen some of the stupid and objectively false things people say? It's not just conservatives.
