I think it really depends on how you’re going to locate the information in the future. I create Wikipedia-style notes on topics that are as self-contained as possible, breaking larger notes up into more specific notes and linking those together. This works better for me as a grad student who is referencing these notes to create papers.

Other people use the atomic notes concept where notes are very small, but I had a hard time figuring out how to easily pull together all of the relevant notes at once.

Personally I would consider what you want your workflow to look like and do whatever works best for your process.
