How To create: Live USB with auto user-logon to desktop, auto connection to WLAN and enabled remote desktop?

I have an old laptop where the display is shot.
It still has an eMMC installed which might contain valuable data?
I want to install home assistant onto it and manage it via GUI.

But first I need to get all data of the eMMC before wiping it.

My idea is to boot from a linux live distro. I somehow need to blindly guess the bios setting to start from usb, but I have another HP laptop here which mich have the same bios settings?
What I need is a linux distro which automatically logs in the user and goes to the desktop environment with a connection to my wlan and a remote desktop connection enabled.

The question is about auto-login, auto-wlan connection and remoted desktop auto enabling. I am OK creating the live-USB

Can you please guide me in the right direction?
