A list of community plugins that I’ve installed since I started using Obsidian:

NameUse
Link EmbedThis plugin allows you to convert URLs in your notes into embedded previews.
DataviewCreate databases like Notion (requires knowledge of Dataview Query Language, but you could always ask ChatGPT for help)
Multi PropertiesAdd/edit/remove multiple properties in multiple notes at the same time
TemplaterTemplating language that lets you insert variables and functions results into your notes
