I used org mode at my last job, lots of management data, deep learning research, and patent application notes. Org worked great for me.

Now except for occasional DL related consulting, I am retired and my tech world activities are centered around writing. I have four book ideas that I will get to in the next few years, and updating my older books to new editions takes time. Keeping notes and research is vital for authors:

Now I use markdown text files for local notes and for cloud based note taking I went back to using Google Keep. I was using Apple Notes until I realized that they used imap to synchronize and that was not secure enough for me. For a decade I had used Evernote, but that ended up being too much ceremony/overhead.

EDIT: Apple really needs to encrypt more types of user data in iCloud.
