Audit and update htaccess file - WordPress

Hi, my website was migrated from a HTML platform to WordPress 12 months ago and I'm very happy with the design of the website. Around 8 months ago I tasked another web designer to audit my Google console data and update my WordPress htaccess file. A big mistake on my behalf.

I feel the current htaccess file is negatively impacting my website SEO and my GSC data is not looking the best. See attached screenshots.

I need a developer to audit my WordPress htaccess file and update using best practice if deemed necessary. I need to see an improvement with my GSC data along with an uptick in website visits. I've been assured this is a quick fix but I will not attempt it.
