Seven services, one piece of work
These aren't seven products off a menu. Most of the time they're stages of the same job, and the order matters: some things make no sense to touch until others are sorted.
The order this usually happens in
You normally start by measuring. An audit tells you what's broken, what already works and what's urgent. Two strands come out of it. The technical side, so Google can reach, render and index what you have. And the content side, so a decent page exists for each thing people search for. Technical tends to go first, because writing excellent pages nobody can crawl is money on the floor.
The next three aren't stages, they're contexts. Ecommerce rewrites the rules on architecture and filters. Multilingual adds a layer you have to settle before a word gets translated. And the Google Business Profile sits apart: quick, cheap, independent of your website, and perfectly sensible to buy on its own.
Not sure where you fit? Website but no diagnosis: start with the audit. Customers who live near you: start with the Google listing. Already been told what's wrong: go straight to that part.
