I'm preparing to erase and reinstall macOS on my Mac hard drive. What are the necessary steps in Xcode to successfully reinstall Xcode and related projects. One thing I have to do is export certificates and later import the same certificates. Is there anything else I am missing?

Essentially this is the same as setting up a new Mac. You will need to import the certs that you had imported.

I use git from the command line to download my apps' source onto the new Mac. The certs are needed so you install your app on a iOS device. For Mac apps, the certs let you upload your app to the app store. Notarized apps need certs too.

From Xcode > Preferences... > Accounts

Select your Apple ID, then click the tiny cog at the bottom of the dialog.

Import Apple ID and Code Signing Assets...
Export Apple ID and Code Signing Assets...

Remember to also transfer your Source Control Accounts (and any associated ssh keys).

You may also want to backup any Themes customisation (stored in ~/Library/Developer/Xcode/UserData/FontAndColorThemes/), and make a note of any Behaviors.

What are source control accounts? and ssh keys?

If you don't know, you are probably not using them!
They appear in Xcode Settings > Accounts (under the Apple IDs section).

Source Control (e.g.):

GitHub
Bitbucket

ssh keys (in this context):

Used to secure the connection to the source control account
