Sorry, but the Windows 95 user interface had the exact same discoverability issue.
Personally I loved force touch and a few months on iOS 13 I’m still struggling with transition to long press gesture instead.
The problem with long press as an accelerator is that it’s triggered by a deliberate pause. It might just be a few hundred milliseconds but the perceived time is very frustrating.
That doesn't change the fact that neither interface gives you a way to know in advance which items have associated contextual menus.
At that point they could no longer use their computer at all until they got external help.

A context menu is fine when it provides shortcuts to functionality also discoverable elsewhere. Windows 95’s context menus were full of functionality only available through them.
See: right click.
I'd say the one thing that MS Office always did really well in comparison is the format paster. Cmd-alt-c/v just isn't as intuitive and discoverable.
So every Mac menu conceivably had (has?) 7 sets of contents, 6 of which are essentially secret. Idiotic.
edit: with my post I in no way wanted to indicate that Apple's UI is the pinnacle of design - just that they IMO made the right choice at first by avoiding context menus, or at least keep them optional.
If you really need it, you will discover it. Otherwise, you can still go to the trash and really delete the file from there. It's safer than having the really delete item by default, and it's there if you need it.
Office products have the worst copy/paste of any software I use. Somehow their rich-format copying never does what I want it to do, despite fussing with setting default paste options and learning the advanced keystrokes.
I was like you, until I learned what each of the pasting modes are meant to do, and in particular that it works different if you copy/paste within the same document or from an external source.

Now I still consider it shitty, but at least I'm moderately in control.
