Kudos for the new website! I like it! Regarding your questions:
We have built several websites with Gatbsy and love it.
We use Contentful - but also have used Strapi.
We also found that integrating Google Optimize does not work without loosing performance or having a flicker effect. Even the anti-flicker effect plugin from Google is not a good option, as it increases the time to interaction which is bad for SEO and UX (in our tests more than 2s in mobile devices).
Note: As we could not combine the performance and ab testing with Gatbsy (and other Jamstack frameworks), we developed a product for personalization and ab testing for this case. To make this possible we use a mix of compile time analysis, code generation, native integration with headless CMS, as well as edge workers.
Here you can find a tech demo of a Gatsby site using our product to personalize and A/B test in just 350ms LCP:
