But I found that the Bottles project pretty much solves this, by installing everything in some kind of sandboxed environment:
https://usebottles.com/
https://github.com/bottlesdevs/Bottles
Has worked wonderfully for the few cases where plain Wine failed.
they don't have sandbox. only if you install the flatpack AND DISABLE SOME CONVENIENCES you actually get something I'd call a safe sandbox.
but their site lies and make you feel safe while being extremely vulnerable installing cracked games (which is what everyone used bubble for).
