This is true, but my Windows experience suggests that the one-set approach to window-switching doesn't help me maintain that grouping. You do get quick switching between recently-used windows, but if I have more than a few (or multiple sets I need to switch between) then they rapidly get jumbled together for me.
What I actually do on macOS, which I felt was too opinionated to mention in my initial comment, is use Spaces (macOS' virtual-desktops feature) to split things up by task. Normally pretty high-level -- a "work" space and a "relaxing" space always exist, but making task-specific ones to focus on is trivial. Then once you're inside a given space, all the tab shortcuts only switch between windows on that space.
