Yes, the installer automatically (and reliably) resizes partitions for you. A minimum of about 70 GB for macOS is needed (anything lower is still possible but unsupported).

Probably one of the smoothest Linux installs I've had in 10 years or so, since you just run the installer from macOS instead of flashing ISO files to an USB drive.
I learned that my option, for a well tested and functioning distro is pretty much Fedora Remix. So I guess I won't be able to use Elementary OS sadly. I hope Fedora is or can be made to look and behave like Elementary.
Just one more question: is my mac hardware (and encrypted data) still protected the way it is protected before installing Asahi on it? Like device/theft protection etc.
My limited exploration/search on this topic kinda says in some way Asahi Linux lives inside the bounds of macOS (even all the data is available/readable in macOS which is fine by me). Is that so?

Apple devices probably have the strongest security model offered by any otherwise open consumer device these days, so yeah: Installing Asahi won't degrade security of the macOS installation.
Note that the Linux install itself will have weaker protection, since e.g. the fingerprint sensor is not yet supported. I also think disk encryption would be much harder to set up due to Apple's boot process (if it's even feasible at all currently).
