Note-taking app recommendations

Hi, I thought this would be a good place to ask about good note-taking apps for while I'm working on personal or professional projects. I worked for a small software company that used Jira and while my opinions on Scrum and agile have changed, I still miss being able to organize my notes according task and add comments to record my thoughts and progress. I don't care for velocity or burn down charts, just the notes. I didn't mind the kanban charts though.

Anyway, are there any smaller apps for personal use out there that would let me do something similar? I didn't like Trello. Probably the only reason for that was aesthetic. There are too many to-do list apps to try all of them. I used Zotero for research in my undergrad but probably not what I'm looking for. I've heard Obsidian is great for all sorts of note-taking. Any and all recommendations are appreciated. Thanks!
