Automated flow & shared fields

Is it possible to create an automated flow, for example:
Once I mark an “Opportunity” status as “closed one” ---- a project is open with the same name as the opportunity?

And in the same topic, is it possible that certain fields, I have both under “opportunity” and under “project” will take the value once, hence, once I fill in the field under opportunity, the same field would automatically get the same value, assuming the opportunity and project share the same name?
thanks

Yes it is possible. But since you do not have experience in coding, I would suggest hire a freelancer to do your customizations.
