On MacOS (at least my older version on a 2015 MBP), Cmd-~ switches between app windows. Totally undiscoverable but knowing that restores a lot of usability.
It helps, but is still fundamentally different behavior. It's now two key strokes Cmd-Tab to Chrome, then Cmd-~ to switch between chrome windows (with no switcher UI).
The windows-y alt-tab at least shows a preview of all windows, and so its one key stroke to tab through everything.
