Rotating passwords only for web services. Vaultwarden does make it easy. Not all services allow 2FA.

I can recommend mopidy and snapcast.
This will allow for a Sonos like setup you are looking for.

If I'm understanding you correctly, you could make use of a shell script for this. Use WGET to download lists, then combine them into a single large file, and finally create a new file with no duplicates by using “awk '!visited[$0]++'”

wget URL1 URL2 URL3
cat *.txt > all.txt (This overwrites all.txt)
awk '!visited[$0]++' all.txt > no_duplicates.txt

It depends a bit on what you want to accomplish, the threat model, the devices in use, and other topics. I think this is a good read: https://avoidthehack.com/best-pihole-blocklists

Possibly Home Assistant is able to cover your devices and needs.

Define which data is from value. I got 68TB of data but realistically only 3 TB are from such value I maintain several copies (Raspi + SSD) and online backup. The rest of data is stored on a cheap server built at a family member and synchronized twice a year. Make sure your systems and drives are all encrypted. And test your backups and redeployment strategy.
