Great suggestion from leland btw. Check also themes/framework from Studiopress these have also build-in Seo tool. It's great if you build more website, you learn how framwork works and it save you time. If you build just only this website, probably focused theme is better choice.
Quality and well-supported SEO plugin is The SEO Framework There is no junk like in Yoast.
Keep in mind, that basic (in most of case also enough) SEO is just HTML tag - Title and Description ... everything else is "advanced" and not always necessary - redirects, sitemap, opengraph ...
Try to avoid also funcy useless things that make worse experience for visitors - all kind of pop-ups, sliders ... Just check WPCHAT as example, no junk, just quality content.
Btw. if you will use Jetpack for whatever reason, you can use their CDN for pictures (I would not do it anyway). If you not sure about Cloudflare, just do a test with it ON and OFF, you will see the difference, bc. Digital Ocean perfoms really good.
The last think, test little bit in CloudWays settings if I remember well there are tons of cache options and similar settings, again majority of them is better to keep OFF.
