if you read what GSC is testing, goal really is to have less slow urls as Google won't penalise you for moderate vs fast
If you have advertising/banners/javascript it will be hard to get fast GSC reported urls. From my calculation my Google Adsense ads account for around 0.1 to 0.4 of my FCP 75% percentile and my average FCP was 1.6-1.7 (now improved to 1.4-1.6 in last 2+ months). So even if I remove Google Adsense ads my closest for mobile speed would be moderate borderlining fast ~1.0-1.2 FCP.
and reason why is GSC is based on Chrome User Experience report (CRuX) real world visitor data, so if you have slow 3G device visitors, you will never get fast 3G GSC reported FCP. For me I have a large amount of non-USA visitors and slower device/ISP connections pulling down my averages.

I get a little confused on this information:
The Field Data says there is not enough real-world data and then the Origin Summary gives some data. Then the Lab Data is different again. This is confusing me! Maybe it is obvious to someone else.
Ok, so what you are saying is that because of the third-party ads, it is unrealistic to get the fast urls. Not sure why my mobile urls are slow. They seem quite fast when using my mobile!

Also if you're using Cloudflare, be sure to enable and use Browser Insights to see your page speed in real world https://community.centminmod.com/threads/cloudflare-birthday-week-2019.18376/#post-77982

Why is the FID of my website so ligh?
FID = first input delay https://almanac.httparchive.org/en/2019/performance#first-input-delay This metric represents the time from a user’s first interaction with a page’s UI until the time the browser’s main thread is ready to process the event. Note that this doesn’t include the time...
community.cloudflare.com
quoting myself
Pagespeed insights's grading score is based on lab data/synthetic while reported field data is real data for that specific url you test. Origin field data is for the entire domain.com/* so average of index, threads, forum display and other urls of your domain.com. That's another reason why i usually don't focus too much on pagespeed insight's grading score as it's only lab data not real world from your visitors.
But improving lab data results, will help with real world somewhat - but won't help if your visitors are on 2G 400Kbps ISP connection and a 10+ year on low end computer for real world field/origin data metrics.

In that case be sure to also frequent CF community forums https://community.cloudflare.com/
Full disclosure, since 2018 I am an official Cloudflare MVP (not paid/staff) but I have been using Cloudflare for 10 yrs nearly.

I figured that might be what the Origin Summary was, but wasn't 100% sure. Nice to have it cemented down, thanks.
I find this speed optimisation thing fascinating, and I am spending way too much time on it! but I kind like crunching the data. It has only been recently that my scores went down that I got frustrated!!

I hate the forum software they use. Discourse isn't it? Yuk!! Lots of sites use that but I like old school Xenforo type styles. I will take a peek though. For some reason, my comprehension goes down when viewing stuff with that forum software.In that case be sure to also frequent CF community forums https://community.cloudflare.com/

Yeah pagespeed + server speed are my addictions but they're also my bread and butter as I do paid forum/server optimisation consulting for a living for past 18+ yrs and worked with some of the largest vBulletin and xenforo forums over the years

Yeah but bare in mind he doesn’t use much add-one, nor has he got a heavy customised theme, nor any ads. They all contribute!
