1. Menu items’s colors
You can go to Dashboard > Theme Settings > Typography > Advanced > there you can create a new Rule by clicking on + Add Rule > then select Main navigation links
from the dropdown > then you can define font-size / colorshttps://prnt.sc/ddx8nHOSf5PC
2. Please go to Theme Settings > Product Archive > Product grid and you can change shop layouts.
3. Sidecart
If you are using Woodmart Header builder cart element and Elementor Pro plugin, you need to disable Elementor Mini Cart
template that is designed to work with Elementor Pro under Elementor > Settings > Integrations > WooCommerce > Mini Cart Template and select Disable. https://take.ms/Ra7Cv
In case you don’t use Pro version, there is an issue with the 3rd party plugins or Cache plugins. Please clear CDN or cache and deactivate all the 3rd party plugins and activate only theme-required plugins on the site and then check the issue. I am sure your issue will be solved. Then Activate the 3rd party plugins one by one and check which plugin is creating the issue for you.
Regards,
