Thank you for bringing this issue to our attention.
We reviewed the behavior and can confirm that Form Customizer is available in SPFx 1.22.x. In fact, your later output from 1.22.1 shows the option correctly:

Recommended Fix

• Make sure you are using node version 22
• Reinstall the generator:

npm uninstall -g @microsoft/generator-sharepoint
npm install -g @microsoft/generator-sharepoint@1.22.2

After switching to a supported Node version, the Form Customizer option should appear normally.
Please let us know if the issue persists after aligning to a supported Node version.

@fowl2,
I wanted to follow up on the SPFx Form Customizer issue you reported with version 1.22.1/1.22.2. Were you able to resolve it after trying the recommended Node.js v22 and generator reinstall steps?

Thanks!

I created a fresh dev container with node 22 and the option seems to be visible.
