OT: Struggle with LCP (Hugo/Netlify)

Hi Guys,
I wonder if you can help me.
I did I think max that I could do to improve my website but I am still struggling with high LCP (Large Content Paint) on PageSpeed (web.dev).

Report

Typically Featured image is reported as LCP (even running Lighthouse locally from Microsoft Edge). I played locally removing Image, then LCP reported as <p>, when this is removed LCP is moved into the header and still getting approx 3.2-3.6 sec.

I even implemented WebP for images that could cause that, but without major change on LCP.

Suggestions appreciated.

Site is hosted on Netlify.

The question is OT. We do not offer support for web optimisation in this forum.

Please search StackOverflow and similar for ways to avoid LCP…
