I just wanted a list of the Bootstrap 5 add ons, extensions, plugins and possibly some themes I've found.

https://github.com/jqueryscript/Bootstrap-5-Design-Resources
https://bootstrap-extension.com/ I wish I could find this on github or any reference for it because getting the scss would be much better to work with.
