I'm pretty sure that's part of what stage manager is for — you can drag windows in the same stage and they operate how you want — but there's too much manual setup required for me to realistically suggest it as an alternative.
There are a bunch of third party tools you can use though, [AltTab](1) is free and tries to replicate windows experience on Mac. [Raycast](2) has a Switch Windows command which also allows direct access to any window via the keyboard (bind to alt+tab if you like) amongst many other features.
