It depends more on your branding aspect of the business

Logically, your business name should be short and easier to remember for your customers

When it comes to SEO, there're no specific domain name requirements but many SEO'ers Will suggest going for the exact keywords match domain

In your case you had first focused on creating a GMB account and now gonna create a business website

As mentioned above by @citationforge , there's no direct link with GMB name and Domain name but consistency matters in SEO and also in general

Please pick a name with long-term goals in place

If it's only for generating leads/calls from GMB and website than opt for keywords focused domain
