For personal activity logs, !ObsidianMD@lemmy.world with a synced folder. It could probably work for a team too.

It’s not the best experience, but it works. It also means that Mastodon users can boost Lemmy posts and other Mastodon users may wind up commenting.

I follow a couple Lemmy communities from Mastodon. If you create a Mastodon account and search for @technology@lemmy.world you can subscribe to new posts, which get boosted into your feed. You can upvote by favoriting a post and you can reply from Mastodon and it’ll show up on Lemmy.

I can also follow Lemmy users, like by searching for mxwarp@lemmy.world and your posts (but not comments) will show up in my feed.

In addition to the ActivityPub plugin, I would add the Friends plugin. When you have both, Friends will let you follow and respond to people via your WP site. At some point I want to make my Masto account followers-only and make my WP blog my public ActivityPub identity.
