I've been a fan of Notion for a long time, but I'm no Notion guru. It's a bit pricey, but I bought the Notion Bulletproof Workspace template and it's been working great, plus plenty of room to grow into: https://www.notion.vip/bulletproof/ I'd recommend checking it out if you're willing to set it up for your company.

It also offer a subscription for updates, but I wouldn't recommend it. I canceled mine last year since 1) updates aren't frequent and 2) after initial setup I don't plan on changing much since the initial template purchase serves us perfectly well, which is why I highly recommend it.
