Form input in 2 languages. Best schema design?

Wow Scott. So punctual and so helpful! Many thanks.
The translation facility will not be required (thank you) but I do have another lingering question…
Can you share a word or three to steer me in my investigation about how to combine the two separate, but parallel, sets of data that I will receive into a single dataset? Maybe an automation that when a French language field is populated it gets copied into the parallel English language field in the same record? (I will have to learn how this might work with the various field types?) Or might there be a better way?
Thanks again.
