Not built in, but Clipy is a good lightweight third-party app (it's a fork/continuation of the now-defunct ClipMenu).
In Clipy, you can customize how many clipboard items it retains, as well as setting up snippet folders for things you paste frequently.
For a writer, I would say a clipboard manager is essential if you do a lot of copy/paste or citations. I use the open-source Clipmenu, but development on that stopped a few years ago; it looks like Clipy is a current fork.
Basically, you can set it to remember several copied items, which can be accessed via a modified "Paste" shortcut. You can also set folders of "snippets" for text or links you use often.
I use it to copy a short bit of text, then copy the URL or citation, then tab over to where I'm writing and paste them individually as needed, rather than going back and forth multiple times (copy text quote, paste; copy URL, paste; etc.).
The biggest hurdle for me was getting used to the Command key being the same as Control in Windows. Being in corporate IT, I've been in a Windows environment for the last 12 years and got very used to command shortcuts like Ctrl+X/C/V, Windows+L to lock my screen, Alt+Enter to send an email, etc. But in the month-ish I've been a Mac user, it's becoming second nature. Command+X/C/V for Cut/Copy/Paste, Alt+Command+Q to lock my screen, Command+Space to bring up Spotlight.
There's some good apps to help with the transition too:
Alfred: Alot of people seem to swear by this Spotlight enhancer/replacement but I've personally not found the usefulness of it just yet
CheatSheet: This one has become one of my favorites. After install, hold down the Command key while in an application and it'll display all the known shortcuts for a specific application. I've not found an application yet that it doesn't show them for. Super helpful when you have an application like Office that the shortcuts aren't exactly the same.
Clipy: Lives in your task bar at the top and lets you look at a number of your recently copied items. Very helpful if you frequently copy and paste multiple items.
Congrats on the purchase!
Two apps that I can't live without on macOS are Numi and Clipy . Also Tumult Hype is a great tool (though more of a niche app)
From the default ones: I tried Automator recently (after several years using macOS) and came away very impressed. Wonder why it's not more well known.
