I suggest you don’t pull the trigger on everything just yet, or else you’ll get burnt out. Desktop environments aren’t dependent on the distro, just find some environments that look like mac os or the ones that you can configure to look and feel like mac os and use them on the distros that you want to try.

start with i3wm/sway or openbox. openbox is a floating window manager so it should be more familiar and i3wm is a tiling window manager. personally i use kde nowadays but i always preferred tiling window managers when i chose to use one. it all comes down to your choices so first see if you prefer tiling or floating window managers and then go from there
