You can add Shift to both Command-Tab and Command-` to move in the reverse direction.
Then you are deliberately handicapping yourself, this isn't something you can blame on the OS. It's like complaining that a car has bad fuel economy because you always stay in first gear.
As for the displays, you are comparing apples to oranges. You can get a high DPI monitor which is smaller than 32 inches for cheap. Which is plenty of screen for the distances where DPI differences are important.
The classic "You're holding it wrong" defense. Especially when the alternatives don't have this problem.
But other than that? Most macOS apps are now inferior to browser-based analogs. Calendar, contacts, email, iMessage, Music, TV - they all just suck.
It’s the dumbest thing apple has ever done and hats off to betterdisplay dev. Best money ever spent on a desktop tool easily.
These don't matter as much when you have high PPI. But they're a lifeline on low PPI displays (and there are a lot of those).
So CMD+TAB+SHIFT cycles in the opposite order of from CMD+TAB, etc.
Maybe this used to make sense when apps were single purpose but I do basically everything in a web browser or a terminal so not being able to bounce between the previously selected window(of whatever kind), as I can with Alt-Tab on linux or windows, is frustrating.
Also Command-` switches to the next window, not the previous one like I would expect.
MacOS removed subpixel antialiasing, honestly for understandable reasons, making rendering on low-ppi displays blurry, but high-ppi displays are still super expensive. I got a 32" 4k monitor(~140ppi) at Costco for $250. A >200ppi display of the same size costs 20x that amount.
