Why not use a live ISO version of something and boot it from a USB, if you need a full set of network troubleshooting tools, the Kali Linux Everything ISO for example will definitely have everything.

Plan sounds alright. A couple of notes.

• Don’t forget your passwords and bookmarks stored in browser when doing the copy over.
• Personally, I’d use Full Disk Encryption (FDE) because it’s a default option on the Fedora installer and is more secure, and well-tested, and easier to configure.
• For your planned installables, I’d keep a list of apps you regularly install in a file somewhere (even better would be a script which installs them all) then when you distro-hop it’s easier as you can just change your script for whatever package manager.
• Some of your apps will store their configuration in your home directory in a dot file, you might be able to copy these over one-by-one for each app.
• Have you decided on Fedora Workstation or Fedora Silverblue? Each have their merits and demerits, and its worth investigating.

If you have a spare solid state drive or a portable HDD (most USB sticks are a bit too slow for a proper install), maybe install a Linux distribution onto that portable device, then you can just boot from that, then you only need to boot switch in Bios to Windows when you need to use it again. This has the advantage of you not needing to setup a complicated dual boot setup. When you are settled in with Linux, open your drive where Windows is located from Linux, copy your files over (don’t forget your bookmarks and saved passwords) and then you can clone your linux install from your portable drive over your old Windows install using a tool such as dd.
