Yea, having trained my muscle memory for at least 10 years on macs, my daily driver desktop is finally a modern Linux distro, and I'm having the most trouble with un-learning the ⌘ shortcuts. On Linux, sometimes "copy/paste" is CTRL-C/V, sometimes it's SHIFT-CTRL-C/V (meaning I need to position my pinky AND ring finger like I'm playing guitar or something). In terminals it's never CTRL-C/V, and once in a while there is an application where it's something bonkers. I kind of miss the universal ⌘ shortcuts that the entire macOS system and all 3rd party apps followed.

I distinctly remember using Microsoft Keyboard Layout Creator way back to replicate Mac way of entering some typographically correct punctuation on top of Polish layout. You could make your own custom layout as well.

However, when I still used Windows 11, I remember there being a variant of US keyboard layout built into the system that included Mac-like way of entering international diacritics. I no longer have access to a machine with Windows, but a quick Google search suggests United States – International might be what you're looking for.

I always use this, maybe it'll help you: https://andrewdunning.ca/Mac-Keyboard-Layouts-for-Windows/

It's definitely a matter of what you're familiar with. As a Linux user I'm able to use the "Compose Character" key (I map the right-hand Ctrl key to it) and then use that to write diacritics just as I used to in my university computer lab in the '90s on DEC VT220 terminals!

It's quite a good system: you press compose-character and then two letters to be combined. E.g. CC/o/" gives ö and CC/a/o gives å and so on. If you don't know the exact combination, you can usually guess within one or two attempts e.g. just now trying to get ç I guessed CC/c/s (š) and then CC/c/c (č) before getting it right with CC/c/,

Apropos of Swedish keyboards, though, when a Mac is inflicted on me, the horrible contortions necessary to get all the usual programming bracket symbols ({[]}) are infuriating. They're a lot less annoying on a Swedish PC keyboard.
