I'd recommend adding plugins one by one, either to solve a problem or as an isolated experiment, to ensure you fully understand what each does. I can vouch for each of these:

BRAT, Datacore, Dataview, Editor Syntax Highlight, Excalidraw, Hotkey Helper, Image in Editor, Minimal Theme Settings, Omnisearch, Outliner, Periodic Notes, QuickAdd, Readwise Official, Recent Files, Relay, Style Settings, Tag Wrangler, TaskNotes, Templater

HTH!
