Speed Up Google Test

Hello,
I have a little problem with my cscart.
I want to get at least 90 mobile points and at least 95 desktop points on the google test page.
The site is on the latest version of cscart and the latest version of unitheme.
I installed the latest version of full page cache and preload image, optimize image etc... but something is wrong.
And the google test are: 50 on mobile and 80 on desktop on most page
I attach the problems.
I'm looking for a person to help me raise the score as high as possible, for a fee of course.
Thanks

Very old scripts (jQuery), not well optimized CSCart resources for example loading by default login scripts (fb connectors, Google Captcha etc.) on every page. Check also server.

I hear you, 98 on Desktop but a measly 48 on Mobile according to PageSpeed Insights

Biggest culprits are excessive javascript and css, tons of unused content gets tossed into the mix.

for example, google recapcha gets loaded on homepage and adds about a couple seconds more to load time

2.8 seconds on script evaluation?

way too much unneeded javascript on there that take forever...

Minimize main-thread work 5.2 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this.
