I personally use Fedilab for Mastodon, but idk if that makes such a difference. There isn’t really a discover feature that I know off, but remember to follow not only people, but also hashtags! This’ll show you stuff you’re interested in, and then you can follow the people posting stuff you like.
You also have a local feed that shows stuff from the instance where your account is hosted, it turns handy especially if you’ve chosen an instanced themed around one of your centers of interest.

Hashtags are key. You can follow hashtags as well as people to find content fitted to your liking. Then you’ll find people using the hashtags that you can follow from there.
