Strongly recommended to all software developers who use macOS: Maccy.

Clipboard manager for macOS which does one job - keep your copy history at hand. Period.

Lightweight. Open source. No fluff.

Shortcut: Cmd + Shift + C to open a clipboard menu with all your recently copied items, plus a search bar for quick grepping.

Hands down this is the best piece of software I added to my workflow in 2023, competing with Obsidian and Things in terms of productivity.
