What if I want to enable some bug fixes, but not others?

Debugify has a configuration GUI accessible by Fabric's Mod Menu. If you don't want to it, there is always the configuration file located at .minecraft/config/debugify.json

Client, or Server?

Debugify includes many fixes for both the client and server (all server fixes also apply to client). So you should definitely use it on both.

Can I include this in my modpack?

Yes! Of course! I even added a little feature in the mod for you! The constant updates may be exhausting to maintain, so I added a config option that defaults new bug fixes to off, until you get round to looking at it.
