What is easier to SEO-optimize, a site on a CMS or on pure HTML?

Question

CMS

Good day!
The task was to make a business card site 1-3 pages, but most likely we will converge on 1. A business card site about the provision of services by a certain company, so in the future you need to optimize the site and, if possible, bring it to the TOP of search in the region. There is experience in creating such sites, both with CMS and pure HTML, but I have never contacted optimization.
Please tell me how it will be easier to do it on CMS (if so, on which one) or HTML?
Thanks in advance for your reply.

Answer 1

It doesn't matter, but if it's really 1-3 pages, I wouldn't bother with CMS

Answer 2

TOP search by region

Top what? "organics"? or just a landing page? for a one-page site, top organics is unrealistic
