More than memory and CPU, you should be concerned with disk performance -
specifically for the database. The slowest part of the system would be
queries to the database, those that are not cached or are fairly large and
therefore require some temp. storage space.
Ensuring it's on high-performance media (SSD/NVMe) is probably very
important.

Other than that, I think a 32GB RAM and 8 vCPUs should suffice. But you can
increase later if needed.
