ntfy and FreshRSS for me. Audiobookshelf recently joined and I am using it daily. (Inofficial probably the Arr stack though 😅)
Make sure to set up an emergency sheet (https://passwordbits.com/password-manager-emergency-sheet/) and have it available at one or multiple safe places.
If it is just for email forwarding maybe a service like https://anonaddy.com/ or https://simplelogin.io would work. Catch-all is even included in the anonaddy free plan as that is something you actually do not want to have enabled 😄 For your custom domain you have to have the lite plan at least though.
After jumping between duplicati, duplicacy, borg backup, kopia I finally settled on Restic a couple of weeks ago.
Using it with resticprofile (https://github.com/creativeprojects/resticprofile) on Linux and Windows which does all the heavy lifting converting the setup from a simple configuration file to restic commands and adding a few options like calling webhooks on specific conditions etc. It is running rock stable so far.
