Must use extensions for a 2024 ecommerce site

Hi all
considering installing the default OC 3.0.3.9 version with php 8.2
Which are the "must install" extensions paid or free (from OC marketplace or elsewhere) to have a site that is:
Appealing
Easy to use and navigate for customer
Fast
Secure
That close sales not only browsing
Search engine and social media optimized
Allows upsells crosssells and promote return customers.
Scalable and eaay to upgrade with future OC versions.

.....feel free to include more attributes.

Thanks
