Stripe integration for simple store (no subscriptions)- Good step-by-step video explainer?

I have an app with just a few items for sale (physical items, not subscriptions). I’ve managed to setup Stripe, a webhook, and through payment links, I have my MVP ready to go.

However, it all feels a bit “underdone”. I would like to add a cart functionality later on, get more structured responses from Stripe, perhaps structure the db better, etc.

As far as I can tell, 98% of YouTube videos deal with SaaS subscriptions, not “regular” stores (which I understand, probably everyone’s using Shopify and the like?)

I also found this complete Stripe course with 10 hours of video, behind a paywall.

But what I would love to find is this fantastic course, but with old-fashioned cart+shipping functionality, not subscriptions…

Any ideas?
