Beware of buying some starter kit to do the job for you. You may end up spending more time massaging the starter kit to fit your use case vs. starting from scratch on your own.

You mention you work with frontend engineering and design, so I'll assume you will be more familiar with a Javascript stack.

The easiest way to get started these days is to use Supabase + Nextjs, using a free template like https://vercel.com/templates/next.js/subscription-starter (this is a very lightweight starter, not like the commercial ones)

Also, consider using LemonSqueezy instead of Stripe, read about what a "merchant of record" is and evaluate if you need it. It can save you a tax headache down the road.
