Setting up a Raspberry Pi for Windows user. What am I missing?

My father asked me to set up a Raspberry Pi with the essentials to try out Linux and potentially ditch Windows if he likes it enough. He specifically requested YouTube, Amazon Kindle, GIMP, Audacity, KeePass, and a text editor like Notepad. I've installed Armbian Debian with the Cinnamon desktop environment. What would you have chosen?

As for the essentials, I'm not sure where to find a list of the most commonly used programs to install. I've just installed what I think he would appreciate, for example, Firefox with uBlock Origin, SponsorBlock, KeePassXC-Browser, and G App Launcher extensions. Now I'm going to see if I can install Amazon Kindle and Notepad using Wine, along with a couple of alternatives like Calibre and gedit. Then I'll set up a Google Drive folder so he can share his files with his main computer until he decides to switch. Finally, I'll use Timeshift to create a snapshot after I've finished setting everything up.

What essentials am I missing? Do you have any suggestions?

edit: I've realized that this is a bad idea. I'll just install Linux on one of his spare x86 computers and explain that many programs aren't available for ARM. Then, after he gets used to Linux, I can install it on his current laptop and maybe move his Windows installation to the spare computer, if I can figure out how to do that.
