Daniel Mendler (minad on GitHub) et al. have some seriously awesome packages. The latest one I’ve fallen in love with that I haven’t yet added to bedrock is Jinx [1]: a fast spell-checker that supports multiple languages in the same buffer, checks spelling of words based off of font-lock class (read: spell checking in doc strings and comments but not in actual code) and a slick interface that makes correcting words a breeze.

I’m so happy to hear you’ve found some helpful things from bedrock! Happy hacking!
