Workflow + Products Base

I want to use AirTable for Workflow (Quotation > Process > Archive) + to get Product list from same base.

Because of Record limitation per Base (we use ~ 4000 records per year) - the only way is Pro Plan (50.000 per base)?

Or I can go with Plus Plan (5000 records per base) using multiple Bases for collecting data from many years? In example one Base could be for Processing, other Bases for Archive (each for specific year). And for each product type - own Base. Is there any way to automatically extract just records with product type “Book” to Base “Book”?
