You can use either legacy form fields or content controls. Which is best will be determined by who is going to use the form and for what purpose - and you still haven't said why it is necessary to copy and paste text in a form.

If the form is used internally in your organisation or you wish to allow access to the parts of the form that are not fields then you can allow the use of macros which are almost essential when working with content controls.

If the form is for use by third parties, you should try and avoid macros, as you cannot force users to allow them to run, which can prevent some aspects of form design from working.

If the form is used for collecting data for processing, then use legacy form fields and process the documents using macros. If you are e-mailing the forms then see also my page about extracting data from e-mail messages.

Like Stefan, I see no problem using tables for legacy forms and I too would use them for laying out complex forms - but I can't think of any reason why I would want to copy and paste from a form.
