The free downloads are slow, but as books are usually small, it is perfectly usable without donating.

GrapheneOS supports disabling Wifi and Bluetooth after some inactivity.

I think it's also possible to do this with the apps Tasker or Automate, but I'm not sure how much they are able to do and how privacy friendly they are.

It is "Pump Up The Jam": https://www.youtube.com/watch?v=9EcjWd-O4jI

The advantage of FreeTube is that if it doesn't work, it can use an Invidious instance as a fallback.

If you mean the work profile:

1. The VPN does not apply to the work profile, i think the app that creates it needs to define a proxy or VPN, otherwise it's a direct connection.

2. I think you can't easily set up a VPN in the work profile, but I never tried it. If you used Instagram with a VPN up until this point, it might be good to continue using it. If you didn't, don't start now if you will stop using Instagram soon anyway.

3. You can "mount"/give permission to read specific folders of the main or work profile on the other one. It's read-only. For example WhatsApp has an option to switch the image selection to the main profile when sending an image.

(I understand the joke, please don't explain it)

That's why you use a VPN/proxy everytime everywhere, not to sound too paranoid.

Of course

Do you have a firewall on 192.168.43.87 that may be blocking external connections?

Based on your previous posts I assume that you use Windows as your server OS. I am sadly unable to help you with OS-level issues on Windows. I am also unfamiliar with the quirks of the Synology OS.

You can check if your *arr-apps run as the same user as the permissions on the share (on the *arr-server). The folder and contained files of the share on the Synology NAS should have read, write and execute (rwx) permissions for the user of the share.

Do you mean that the automatically grabbed torrent is slow in qBittorrent? The apps themselves don't have any idea what is a popular or unpopular torrent, so it may have just grabbed an almost dead one.

You may want to check out TRaSH Guides for some good Custom formats and guides for the *arr apps.

I recommend finding some good release groups and setting them to be always preferred over others.

You need to add your *arr apps to Prowlarr. Add them in the tab "Apps" and use "Full Sync" as the sync level. If everything works, Prowlarr should add all indexers to the apps after a short while.
