The way I think of it across the fediverse as a whole:
Upvote/Favorite = I like this and I want OP to know
Boost = Other people need to see this
So like low effort memes and off-topic jokes that make me laugh will get an upvote. A thoughtful take, useful information, or something really funny will get both.
I'm still not sure what the difference is. Boost is related to "microblogging" or something?
And if there's both upvotes and downvotes, why isn't there a "diminish" choice that's the opposite of boost?
Lemmy tries to present content in the same format as Reddit does.
On kbin, you have functionality that roughly mirrors Reddit as well as functionality that roughly mirrors Twitter.
On Reddit, you upvote or downvote a given comment or post.
On Twitter, you "retweet" it -- basically, re-send a link to the tweet to the people who follow the microblog that you write.
kbin can present content in both ways.
The way I use them:
Upvote: "This is a good comment in the context of this discussion."
Boost: "Oh, man, this is important. More people should know about this."
If you regularly boost content of a given sort, then people who want to follow your microblog will see related content that they may be interested in.
Here's a list of things that I have boosted:

If you decide that that's especially in-line with things that you're interested in, you could follow that.
