I know this is an old school problem but I have tried digital note taking and it just doesn't work for me.
It will likely take a few days where you will need to answer questions, handle edge cases before your virtual assistant is up to the speed.
And that’s about it. Anytime you want your notes to be transcribed, you just send it through email or whatever
The most digital option would probably be the Ink-to-Text feature of MS OneNote or with a Boox tablet there is an option to input Handwritten words which will then be translated to formatted word, similar to Google Handwriting input android app.
Do you know about the remarkable2? (I don't own one but I am very intrigued)
Email me if interested, my email address is at my profile.
