I have compiled a list of places to go for more learning for improving Accessibility as you develop. I recommend placing Accessibility in your team's working agreement, and in every definition of done.
My personal favorite resource has been Marcy Sutton's accessibility training. My company sent me to several Accessibility training courses she offered, and I have access to her self-guided training through the link above. She's a developer who is passionate about Accessibility. Her classes feel very natural and are much more practical than theoretical.
Below are a 📚 collection of resources I have gathered over the last year as a developer. I will try and keep this updated as I go.

W3C Accessibility Fundamentals
Deque Accessibility Webinar on WCAG & Section 508
WCAG
The Web Content Accessibility Guidelines ( WCAG) are part of a series of web accessibility guidelines published by the Web Accessibility Initiative (WAI) of the World Wide Web Consortium (W3C), the main international standards organization for the Internet.
W3C has recently announced that WCAG 2.2 is scheduled to be completed and published in Q3 2023.
The content for WCAG 2.2 has been finalized and WCAG 2.2 W3C Candidate Recommendation Snapshot was approved for publication in January 2023.
Every year WebAIM runs accessibility evals on the homepages of the top 1 million sites. This is using the WAVE-standalone API

Automatic tests are wonderful but you should not rely solely on those below. Work to build a real understanding of the disabilities you are likely to encounter and view your project through those lenses.
