I don’t feel like leaving the PG community at the moment, but here are a few suggestions that come to mind after reading your list.
Search: SearXNG
MacOS Firewall: Lulu
DNS: NextDNS
Email Alias: AnonAddy
2FA: Remove Ravio (sold to sketchy app maker MobiMe). I consider this compromised until proven otherwise.
YT Proxies: Yattee (iOS App)
File Encryption: Cryptomator (File encryption app, optimized for the cloud)
Notes: Joplin
Podcast: Podverse
To add to this, I suggest sorting the comments by controversial on Reddit for another take.
