In many ways, Mastodon feels like rewinding the clock on social media back to the early days of Twitter and Facebook. On the consume side, that means that your home feed has no algorithm (this can be disorienting at first).
Practically, it means that you see only what you want to see and only see it linearly. You never wonder “why am I seeing this and how do I make it go away?”. Content can only enter your home feed via your followed tags or handles and the feed is linear like the early days of social media.
The low-hanging fruit is sometimes checking out posters that show up in your feed because someone you do follow boosted their post. This sort of amounts to having the people you follow nominate people for you to also follow.
(fwiw, boosting a post just shares it to your followers, liking it just notifies the poster that you liked it)
