Only office? Hahaha. Only if you never have to share a document.
Onomatopoeia
Hahahahaha, damn Google.

Yea, if you use Tailscale with Funnel, you get a secure connection with no config required by the web user.
Not seeing why you need WordPress.
The safest way I can see to make a secure connection across an untrusted network is to use a VPN of some sort, specifically a mesh network like Wireguard or Tailscale.
Tailscale has the advantage of being almost zero config, plus has the Serve and Funnel features which provide a mechanism to allow specific traffic into your Tailscale network.
Edit: Tailscale Serve is probably what I'd use.
To tack on to this, with an example that is easier to grasp - I have my own cloud, comprised of machines at my house, my friends, and family.
Those machines provide backup storage for each other, over the internet (using an encrypted connection).
If I were to charge people for storage, I'd be little different than any other cloud storage provider (at the most basic level).
Your second point is why paying for such services makes a real difference.
Companies like storj.io, backblaze, or any other cloud storage/backup provider provide a service for a fee with (not really) clear usage rules. If you're encrypting your stuff before it goes to the cloud, you're pretty safe from scanning, and if you have a contract for a given space and bandwidth, the worst you'll probably run into is overage fees.
"No longer"?
You just now realize this?
After (ugh) 30 years of having PCs and many, many, drives, Seagate has been the worst.
But I've had WD fail too. Just not as much, and I've had far more WD drives. I currently have about 20 drives of varying ages, 98% of them are WD, because more of the Seagate drives have failed and been trashed.
My only issue with Grayjay (both Android and Windows app), is you have to manually export the videos out of Grayjay
If you try to grab the files directly, they don't work.
The negativity is about like saying I should not exist.
It's your choice to see it that way.
It's up to the squatter to actually spend the time and money to sue though.
A C&D is a letter from a lawyer to stop or they'll sue, it's not a court order.
