Loved the video! Glad you decided to give Bitwarden a try. I have been running it for a year now and it is great.
Have you looked at Bitwarden_rs?
It is a Rust implementation of Bitwarden and it is much lighter. It can run SQLite or MySQL DBs.
Personally, I use the MySQL version becasue I can use standard MySQL dumps to backup my database and easily import it to any MySQL server.
This implementation also works with all Bitwarden Apps (Browser app, Mobile App, and Desktop app) and it has the full web vault.
Here is the GitHub for it: https://github.com/dani-garcia/bitwarden_rs
There are Docker images available for both SQLite and MySQL options.
