Looking for some Google Workspace alternatives

After my private Gmail was leaked somewhere, I've started to receive an enormous amount of spam that came through into my inbox, which made me switch to Proton and a self-hosted SimpleLogin setup.

So I decided, I might as well dirch Google entirely, for private and work-related stuff.

While Proton already covers Mail and Calendar, I'm in search of alternatives for the following services to replace.

• Meet: I like the idea of starting a quick meeting by simply sending a link to a customer, who can join instantly. What would be an equivalent software to do that? I tried Mattermost, but it seems more like a Slack alternative, with invites, etc. and is overkill for my case. Revolt chat looks like a Discord alternative.
• Drive: In short, If possible, I'd prefer one consolidated place to access and edit files. Docs, Excel, PDFs, pictures, videos, etc... Is Nextcloud really the only option here, with the corresponding plugins for onlyoffice and memories (photos)? I tried running thst on an intel nuc, and it's slow as hell.
