This is how I mainly used Mastodon before Lemmy. It lets you follow topics instead of people; I prefer finding content this way. Unless a person really likes the format of Mastodon better, I’d suggest Lemmy over Mastodon for people that would rather follow topics than individuals.

Those are actually not groups. Groups boost posts from all users that mention them. https://a.gup.pe/ is one implementation of groups with mastodon in mind, but lemmy communities actually work the same way when followed from mastodon. I believe other fediverse platforms implement groups in similar ways under the hood. This means that everything is more or less interoperable between platforms.

Tusky is a great app. But it doesn’t seem to have a trending tab, which I use to find cool accounts to follow. For now I use trunks.

Another good thing is putting people you follow into lists. I just wish we could do the same with hashtags.
