Do a test using Pagespeed, and identify the files containing the errors.
To find the keyword you can either use the asset name or use Chrome Dev Tools; click F12 on Chrome, click the “Network” tab, and hover over “Initiator” to see which file triggered the asset loading:

Delay using WP Rocket
Delaying any 3rd party plugins will also fix the Pagespeed “Reduce the impact of third-party” warning.
If you haven’t bought Wp Rocket yet, consider using my reflink.
(?:wp-content|wp-includes)(.*) /jquery-?[0-9.]*(.min|.slim|.slim.min)?.js js-(before|after)
The reason behind this formula is as follows:
- /jquery-?[0-9.](.min|.slim|.slim.min)?.js – excludes jQuery
- js-(before|after) – exclude inline scripts. Only inline scripts that are added using wp_add_inline_script() will be excluded.
Switch to better plugins

Read here how Instagram improved their infinite scrolling feed performance with 25% reduction in time taken to load photos using task priorization and other techniques.
Consider using a smaller captcha such as math challenges, instead of Recaptcha. Setup Cloudflare and enable bot/email protection if it suits your spam/bot fighting.
You also can delay ReCaptcha until user-interaction to reduce js exec time, but it needs testing, as smart bots may trespass this option.
Ask the developer to improve the plugin
