Ishant Hello Heather here I hope you are well. When you add any information or content to the page it has an impact on your sites speed as it adds an extra 'hop' to the whole process. Ezoic is a Google adsense partner and so we place our ads on sites with lazy loading which is inline with Google policies and means that the ads load last.
In terms of your site I can see that currently your site doesn't have enough data to have real world results and so Google is using lab data which is a mathmatical approximation as to what Google thinks your data is.
We generally find that when the core web vitals are based on real user experience data the core web vitals improve and the FID is generally green.
This blog post talks you through this in more detail: https://www.ezoic.com/lab-field-and-origin-data-whats-the-difference-and-how-they-impact-core-web-vitals/
For your next steps to take I would recommend working through each step in this document and then waiting till your sites real world data starts to show in Leap and then go from there https://community.ezoic.com/d/3808-access-now-success-how-do-i-get-my-core-web-vitals-to-green
If you have any questions please do let us know. many thanks
