Brick and Mortar Retailer / Integration in Klavyio

We are new to Klaviyo and are a brick and mortar retail chain with 100+ stores. We have been scouring the developer documentation trying to understand how we should properly map our many events and properties that are based around brick and mortar interactions. I have found info on mapping purchases and purchase item events for online orders but what about in-store (also store where the customer purchases more frequently, last purchase store, first purchase store, etc)? I want to ensure I can use as much native Klaviyo functionally as possible without doing custom events that I map to my business needs (I would much rather make my business needs fit to the Klaviyo formats). Any advice or recommendations from other brick and mortar folks would be greatly appreciated!
