Apple Notes with ProNotes and Readwise Reader would work for most people.

Unless you have very niche needs and interests. Otherwise overthinking and tinkering is what prevents most people, if online discussions and videos are to gauge by, of utilizing their notes well.

In an ideal universe, if we want our notes to have lasting value, it makes sense that they should be very easy to capture, write and revisit. Nice to have features would be being able to interact with various other core apps (productivity one's) and capture a healthy variety of content. And then off we go.

It's a cliche here but trying to find the perfect all in one solution at all times is a time and money sink that's an overkill for most, emphasis most, folks.

Apple notes now has solid audio transcription. You can transcribe calls too. With ProNotes you can write in markdown plus easily get a shareable link to notes, which makes integration with Calendar, Reminders, or task managers like Things 3 a breeze. Has solid OCR. Fast, free, and quick notes makes capture speedy too.

If you want to capture and revisit ideas and documents, it's honestly fine. And now it has a native Readwise Reader integration if you want to remember or revisit web content.

For most people, these use cases fullfil their needs. It isn't perfect but the 80/20 rule applies here well. Its core functionality is more than enough for what people think a Second Brain or PKMS should be.
